I created a venv on Windows and tried to run

python -m osnap.osnapy

But osnap/utils.py requires requests.

Update osnapy to use pkg-config to locate openssl, or perhaps to hard-code brew --cellar [email protected] .
(There are lots of reasons that /usr/local might be a bad choice. @glyph)

With the current code, appdirs should be added to setup.py. But it would be better to just use balsa.

I'm running windows 10 on a VM on a mac.

It's 32-bit on an x86-based processor.

I ran

python -m osnap.osnapy

using python 3.5.2 I get the following:

Z:\temp>python -m osnap.osnapy
get https://www.python.org/ftp/python/3.5.2/python-3.5.2-embed-amd64.zip to cache\python-3.5.2-embed-amd64.zip

For very simple programs there may be no external requirements. In that case OSNAP still requires that requirements.txt be present. If the file is empty, which it should be, we get an error from pip about an empty file

I accidentally ran the installer builder when my script was called 'goo.py' rather than 'main.py'. It still produced an exe and an installer. I had to dig through the output to notice that it emitted an error log indicating I didn't have main.py. it'd probably be best to fail the whole process at that point so users don't waste time as I did looking at the produced output that will never work

Probably the best comparison of Python freezers is available here, on The Hitchiker's Guide to Python. In the pursuit of better osnap publicity, I recommend submitting a PR to add osnap (and maybe also a column indicating whether each project is maintained. bbfreeze, for instance, is not :) )

I'm slowly working my way through getting this project working and hitting some stuff that's a little frustrating. OSNAP does a bunch of processing before getting around to a cryptic stack trace about the failure rather than checking upfront if everything it needs is there. This includes:

a directory named the same as my application name that it wants to copy. In my case my sample application is called 'goo' and it wants a folder named 'goo'. It was happy as soon as I added one with an empty init.py in it

a LICENSE file. Also can be empty, I think
an icon file, again, based on the name of the application. Such as 'goo.ico'
NSIS installed at C:\Program Files (x86)\NSIS\makensis.exe

there's no summary in the tagline on the project :)

I have no need for an NSIS installer when I build because I use my own WiX installer. I'd like to avoid the requirement of having NSIS installed on my build machine. Let's create a commandline switch to disable the NSIS installer. This will maintain the current default behavior but just optionally disable this step of the packaging process

Here 2e4a7f7#diff-e272fd5500f2ed699f985d24b5403b06R10 you say that you can't install pip when using the embeddable zip file version of Python 3.6.0.

How are you installing pip?

I tried both python.exe -m ensurepip and python.exe -m pip install pip and neither of them work in Python 3.6.0 or Python 3.5.2

Perhaps I missed it in the documentation but I didn't see anything about installing whatever packages build is. On OSX El Capitan I get the following exception.

raise CalledProcessError(retcode, cmd)

subprocess.CalledProcessError: Command '/usr/local/bin/packagesbuild pathlt.pkgproj' returned non-zero exit status 127

After a little bit of googling around it looks like this is or was part of xcode. I have xcode installed but this doesn't seem to be on my system. The docs should probably call this out explicitly with some installation instructions similar to NSIS

While I was working on the project I noticed that OSNAP uses py2exe under the covers. I don't think that's really a problem, but my initial review of the technology led me to think that OSNAP was a simpler replacement for py2exe using the new embeddable python shipped with recent Python 3. Now I'm not so sure. What are the advantages of the project over using py2exe directly?

You can consider this issue a request for documentation, but mostly I just wanted to talk to you about it since I'm in the process of evaluating exactly which way our company will go with freezing technology for our next project and I want to make an informed decision.

I am trying to package an app, but I keep getting an error about version
PycharmProjects/qt-projects/PyQt-projects/SR/osnap_setup.py", line 9, in make_installer

AttributeError: module 'main_app' has no attribute 'version'

Currently OSNAP uses launchwin as the underlying bootstrapping process for executables it produces. launchwin is checked in to git as a 64-bit binary. In many situations it's nice to build a 32-bit binary on a 64-bit machine so that the binary will work correctly on a broader base of windows installations. OSNAP should support an option to build a 32-bit binary by force no matter what the system architecture is. This will mean maintaining two different versions of launchwin for bootstrapping in the repository

Hey I'm trying to build an installer for this code.

Explicitly looks for main.py in the current working dir. I assume this is used as the main entry point but not all packages uses main.py as the entry point. If this is an actual requirement it should be documented.
