I wonder if it's because the pkgs.pickle file has references to /home/vineet/.virtualenvs/equimapper/src/lookupy and such in it? Maybe it works on your system, but not others because of this?

Possible bug: json output different to bare output

Hi guys, I think there is a weird difference between the json output and the bare output, I'm not sure though, but it looks like the trees generated are different.

I created a simple requirements to show an example:

$ cat requirements.txt 
flask
flake8
ipdb
ipython
pep8

It looks like the json output does not have any nested elements like the bare version. If you check the six package in the bare output it's nested very deep inside ipdb but in the json it is not nested, it's just a dependency of prompt-toolkit at top level.

This is the json output

Removing a package + its dependencies

Good afternoon!
Is there a strategy to find unused decencies of a package and remove the package and all those dependencies?

KeyError: 'py'

When running pipdeptree on one of my virtualenvs, I get the following error

$ pipdeptree -a
Warning!!! Possible confusing dependencies found:
Traceback (most recent call last):
  File "/home/stefan/soco/SoCo/venv32/bin/pipdeptree", line 9, in <module>
    load_entry_point('pipdeptree==0.4.1', 'console_scripts', 'pipdeptree')()
  File "/home/stefan/soco/SoCo/venv32/lib/python3.2/site-packages/pipdeptree.py", line 245, in main
    req = non_top_pkg_name(d, pkg_index[d.key])
KeyError: 'py'

I can provide a copy of the virtualenv if required.

No warning should be issued when a package is required by two packages, one requiring a specific version and the other not

I'm getting the following warning:

Warning!!! Possibly conflicting dependencies found:

cryptography==1.4

setuptools [required: >=11.3, installed: ]

zope.interface==4.2.0

setuptools [required: None, installed: ]

repoze.who==2.3

setuptools [required: None, installed: ]

protobuf==3.0.0b2.post2

setuptools [required: None, installed: ]

But I think no warning should be issued here as all packages but the first require just any version of setuptools.

Great Tool - Get it into pip as pip deptree :)

This is awesome! Let's see if we can get this into pip itself via pip deptree :)

pipdeptree cannot run with pip 10 as get_installed_distributions is gone

Running pipdeptree with no arguments with the recently released pip 10 results in this:

Traceback (most recent call last):
  File "/home/cdown/.pyenv/versions/3.6.3/bin/pipdeptree", line 11, in <module>
    sys.exit(main())
  File "/home/cdown/.pyenv/versions/3.6.3/lib/python3.6/site-packages/pipdeptree.py", line 550, in main
    pkgs = pip.get_installed_distributions(local_only=args.local_only,
AttributeError: module 'pip' has no attribute 'get_installed_distributions'

This seems an intentional API restructuring, see pypa/pip#5154.

Case sensitivity issues

If I use this in a package:

install_requires=[ 'shapely==1.5.17.post1' ]

The package installs fine, but the pipdeptree graphviz output has an extra root node with Shapely.

Fixing my package to match the case for this library on pypi works around the issue (install_requires=[ 'Shapely==1.5.17.post1' ])

Support user dir

It would be nice to support user directories as in pip install --user

* Edited

pipdeptree -l is broken - doesn't seem to respect local virtualenv

See: http://codepad.org/j5MwjQYt

There is some discrepancy here between what pip freeze thinks is local and what pipdeptree -l thinks is local.

Support using with both Python2 and Python3 installed

I would like to execute pipdeptree on both my Python 2 and Python 3 installations. Currently this is not possible, since the script installed into /usr/bin/pipdeptree is "bound" to a specific python version using the #! hashbang at the top:

#!/usr/bin/python2

# -*- coding: utf-8 -*-
import re
import sys

from pipdeptree import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

I guess we can solve this by two ways:

Rename the installed script to pipdeptree2 if it's installed using Python 2, and ln -s to pipdeptree. For Python 3 we'll have pipdeptree3. This will allow the user to keep the two versions.
Put them somewhere else e.g. in the Python system directory tree and link them to /usr/bin/, so the user can soft link/alias the scripts as he wishes.
Any other idea?

Listing packages by dependency?

Is there any built-in option to only list packages that have a specific dependency?

I want to upgrade my version of Django, so I'm trying to find which packages I have installed depend on Django so I can check them.

I see there's a --packages option, but this only filters by the top-level package, not dependency.

Changes in pip-10.0.0b2 break pipdeptree

pipdeptree is broken with pip-10.0.0b2.

$ pipdeptree -j
Traceback (most recent call last):
  File "/home/someone/venv/bin/pipdeptree", line 11, in <module>
    sys.exit(main())
  File "/home/someone/venv/lib/python2.7/site-packages/pipdeptree.py", line 550, in main
    pkgs = pip.get_installed_distributions(local_only=args.local_only,
AttributeError: 'module' object has no attribute 'get_installed_distributions'

I believe this is due to the following item in the change notes for pip:

Move all of pip's APIs into the pip._internal package, properly reflecting the fact that pip does not currently have any public APIs. (#4696, #4700)

Python 3.3 and 3.4 traceback

Works fine on python 2.7.8 but on both 3.3.5 and 3.4.2 I get the following traceback:

Traceback (most recent call last):
  File "/Users/jp/.virtualenvs/python3.3/bin/pipdeptree", line 9, in <module>

Confusing Dependencies section should not display non-conflicting dependencies

For example:

* django-guardian==1.2.2 -> Django [installed: 1.6.5]
  djrill==1.0.0 -> Django [required: >=1.3, installed: 1.6.5]
  django-mptt==0.6.1 -> Django [required: >=1.4.2, installed: 1.6.5]
  django-cors-headers==0.12 -> Django [required: >=1.4, installed: 1.6.5]

All of them require Django above a certain version. Since none of those packages limit the Django version in use there is no conflict (Django 1.4.2 and above is required).

pip refactoring will break pipdeptree

@dstufft has decided to move around the imports in pypa/pip#4700, which will necessitate adjustments to the imports in pip 10.0.

Option to limit depth of the dependency tree shown

It would be nice to have an option -d N or --depth N to limit the depth of the tree shown either in direct dependencies or reverse.
This would also help to find packages left behind when other packages are removed (leaves).

Release checklist

Please release/tag 0.8.0 here on GitHub too.

Thanks.

Need dependency additions for distribution packaging

The distribution package for pipdeptree does not check for the required module argparse, and it installs on Python 2.6 but will not run in that environment because of some apparent Python 2.7 features (i.e., what I believe are called "closures" in dictionary assignments).

Please note that I'm not asking for pipdeptree to support Python 2.6, just that the package information on the project page and the packaging itself inform the user that the package needs 2.7 and the argparse package.

Inconsistent order of dependency requirements

I've come across an issue where the order of the required dependencies seems to be inconsistent, in that sometimes it is listed as:
package-name [required: <x,>=y, installed: z]

and other times as:
package-name [required: >=y,<x, installed: z]

Why is this an issue?

I realise the above two outputs are equivalent, though I personally like to check this requirements output into version control, to track requirements changes during development. I therefore only really want to see changes to the pipdeptree output (> file), if the dependencies actually change.

Steps to reproduce:

virtualenv 'pipdeptree_ve'
source 'pipdeptree_ve/bin/activate'
    pip3 install \
        'flake8' \
        'pipdeptree'

    # I'd expect the output of each of these commands to be the same/consistent
    pipdeptree
    pipdeptree
    pipdeptree
deactivate

Expected behaviour:

# i.e. for the output to be the same each time.

- idna [required: >=2.5,<2.7, installed: 2.6]
- urllib3 [required: <1.23,>=1.21.1, installed: 1.22]
  but json format urllib3 appears as a first level node
  [
  ...
  {
  "dependencies": [],
  "package": {
  "installed_version": "1.22",
  "package_name": "urllib3",
  "key": "urllib3"
  }
  },
  ...]

but I wanted to prune the dependency tree based on "provided by container" dependencies
assuming, in this simplified example that 'requests' is 'provided' at runtime on the path

I wanted to prune the json tree so that urllib3 is not included

Not a big deal - I will use the text tree output for my pruning

No output for a virtualenv with a bunch of Zope packages

I was trying to create a state with circular dependencies using some Zope packages to reproduce the infinite recursion error that I mentioned in #10 -- I found this page, which mentioned that Products.OFSP==2.13.2 and Zope2==2.13.19 had circular dependencies.

Instead I found a state, where pipdeptree prints no package tree even though a ton of packages are installed.

wsgiref==0.1.2

Note that outputs a bunch of warnings, but the only thing it really lists is wsgiref.

Suggest change `project_name` to lower case

Suggest change project_name to lower case, since pip package name is case insensitive.
Packages like Pillow, Pygments and PyYAML often has different spellings in other package's dependency list. This will reduce isolated packages / dependencies produced by pipdeptree.

This change only need to add four lines in build_dist_index:

    for p in pkgs:
        p.project_name = p.project_name.lower()
        for r in p.requires():
            r.project_name = r.project_name.lower()
    return dict((p.key, DistPackage(p)) for p in pkgs)

Incorrect reverse dependencies when a package is required multiple times

Within a fresh virtualenv, install pipdeptree, and then dateutil and cycler, which both depend only on six.

$ python -mpipdeptree -r
six==1.10.0
  - cycler==0.10.0 [requires: six>=1.5] # Oops, this should be dateutil.
six==1.10.0
  - cycler==0.10.0 [requires: six]

Produce indented output for requirements.txt

Would be cool if pipdeptree could produce indented output suitable for requirements.txt, like this one:

aspen==0.37
   filesystem_tree==1.0.1
   first==2.0.1
mimeparse==0.1.3

pypa/pip#2918

`--freeze` command skips important packages

This is intentional, but I'm not sure why: https://github.com/naiquevin/pipdeptree/blob/master/pipdeptree.py#L418

This makes pipdeptree --freeze insufficient as a replacement for pip freeze despite how much nicer it is.

I'm happy to do the PR if there's agreement that all packages should be listed. Just found this project today and got a few other PR ideas - pipdeptree is really helpful!

pipdeptree believes that "setuptools" is an unknown dependency

e.g. after installing twine and pipdeptree in a fresh virtualenv:

$ python -mpipdeptree
Warning!!! Possibly conflicting dependencies found:
* twine==1.6.5
 - setuptools [required: >=0.7.0, installed: <unknown>] # A recent setuptools is available.
------------------------------------------------------------------------
twine==1.6.5
  - pkginfo [required: >=1.0, installed: 1.2.1]
  - requests [required: >=2.3.0, installed: 2.9.1]
  - requests-toolbelt [required: >=0.5.1, installed: 0.6.0]
    - requests [required: >=2.0.1,<=3.0.0, installed: 2.9.1]
  - setuptools [required: >=0.7.0]

Option for reverse mode

pipdeptree displays all packages with their dependencies. I would like to see all packages with their dependents, to answer the question “why is X installed”. What do you think?

handling of extra_requires

scikit-image (https://pypi.python.org/pypi/scikit-image) depends on dask[array] (https://pypi.python.org/pypi/dask) (not visible on PyPI but this can be checked by installing in a clean venv). dask[array] itself depends on toolz and numpy.
pipdeptree does not realize this and considers toolz and numpy to not be dependents of anything after a clean install of scikit-image.

I'm not exactly sure what is going on, but an exception handler may need to be implemented.

List all "root" packages, even ones without dependencies

Hey naiquevin,

In one of my virtual environments I have the cx_Oracle package installed. It requires no dependencies, and isn't a dependency of any other package. However, when running pipdeptree with either the -a or -r flags, this package isn't listed. Wouldn't it be useful for it to be listed?

What I want is a list of all my "root" packages, that is, packages which may or may not have dependencies, but aren't a dependency of any other package themselves. That way, I can simply output this list to my requirements.txt, making it shorter.

I'm willing to submit a PR at some point in the future if you have interest in this feature but lack the time to implement it yourself.

Thanks in advance!

KeyError is thrown if an installed package depends on pip

I have the library pbr installed, and because it depends on pip, pipdeptree throws an error when trying to print out possible confusing dependencies. I think you just need to exclude any requirements that are in the skip list. Here's the traceback I get:

Traceback (most recent call last):

--reverse not working anymore in 0.10.0 ?

Hi there,

I just upgraded from 0.9.0 to 0.10.0 and I noticed that the output of my usual command is different:

0.9.0

pipdeptree --packages mando --reverse

mando==0.3.3
  - radon==1.5.0 [requires: mando<0.4,>=0.3]

0.10.0

pipdeptree --packages mando --reverse

mando==0.3.3

Example project: https://pypi.python.org/pypi/radon

I tried with both -r and --reverse, same problem, I think something broke.

Allow to run without installing into virtualenv

I'd like to have pipdeptree installed once (using pipsi), and then be able to use it in a different virtualenv.

Is this a use case you'd consider supporting?

None -> Any requirement

Could we say Any instead of None in this?

  - requests [required: None, installed: 2.11.1]

Minor improvements to output readability

A few suggestions:

(recursively) sort the output, instead of having the packages in a semi-random order
provide a switch that allows limiting the depth of dependencies (possibly using [...] as a marker for "deeper dependencies not shown here) or hiding the installed version.
provide a switch for listing packages that are not dependencies of other packages.

Nice work!

False "Possibly conflicting dependencies found" warning

Warning!!! Possibly conflicting dependencies found:
* cryptography==1.5
 - setuptools [required: >=11.3, installed: 27.1.2]

I have pipdeptree 0.7.0 and of course setuptools 27.1.2 is installed.

Option to exclude setuptools and its deps from output

Since setuptools v34.0.0 now requires dependencies explicitly, can setuptools and the usual brethren (pip, wheel) be excluded from output with an extra arg, or maybe define a --packages_to_exclude

Add mode to run on requirements.txt

It would be really convenient to run on a requirements.txt file, because right now I'm hitting a compilation failure installing a library that isn't a direct depedency but a transient dependency, and I don't know what pulls it in. I'd like to bump the direct dependency so I'm on the latest version of the transient one

Allow showing additional package metadata alongside name

How difficult would it be to add a --license command line switch and then pipdeptree would output not only the package name and version but also the contents of the LICENSE metadata field?

combine --package with --graph-output

Dear Vineet and colleagues

Great idea and wonderful program!
It would helpful to be able to plot the graph of antecedents to a package or set of packages.

Thanks
Arthur

The reverse view should group all the packages that require a certain package together.

When using pipdeptree -l -r, it's confusing to see the same package listed multiple times in the (long) list of required packages. It can lead a user to incorrectly think a package is only required by one package, because they didn't notice the package is listed again elsewhere in the output.

Also, the same dependency is sometimes listed more than once. For example, I get:

six==1.10.0

protobuf==3.0.0b2.post2 [requires: six>=1.1.0]

gcloud==0.12.0 [requires: protobuf]
six==1.10.0

protobuf==3.0.0b2.post2 [requires: six]

gcloud==0.12.0 [requires: protobuf]

And sometimes I also get seeming contradictory dependency listings (yes, I did use -r -l here too):

six==1.10.0

Paste==2.0.3 [requires: six>=1.3.0]

pysaml2==4.0.5 [requires: Paste]
six==1.10.0

Paste==2.0.3 [requires: six>=1.5]

pysaml2==4.0.5 [requires: Paste]

Use filled node with different color for graph output

Use filled node with different color for graph output, make it's clean for top level package and it's dependencies.

Changes in dump_graphviz(tree, output_format='dot'):

    dependencies = set()
    for deps in tree.values():
        for dep in deps:
            dependencies.add(dep.project_name)
    graph = Digraph(format=output_format)
    for package, deps in tree.items():
        project_name = package.project_name
        label = '{0}\n{1}'.format(project_name, package.version)
        attrs = {'style': 'filled'}
        attrs['color'] = 'lightblue' if project_name in dependencies else 'green'
        graph.node(project_name, label=label, **attrs)

Infinite recursion error when packages have a circular dependency

If there is a circular dependency in your packages, then pipdeptree dies with an infinite recursion error.

One way to reproduce this:

$ virtualenv circular_deps_Zope2.venv
New python executable in circular_deps_Zope2.venv/bin/python
Installing setuptools, pip...done.

$ circular_deps_Zope2.venv/bin/pip install pipdeptree Zope2==2.13.19
...

$ circular_deps_Zope2.venv/bin/pipdeptree --all

Python 3.4.x issue

I'll make a PR for this issue.

When I try to run pipdeptree with output of png, svg or pdf, it tells me that Graphviz is not installed, but it appears to be already installed.

Limit to individual project directories

It would be nice if the dependency reporting could be limited to a specific project directory. Usually, I'm not interested in all dependencies of all packages, but only in the (transitive) dependencies of a specific project, ideally even before having installed any of the dependencies.
