fatal: Unable to find remote helper for 'hg' about git-remote-hg HOT 12 CLOSED

Do you have execution rights for git-remote-hg?

from git-remote-hg.

Yes:

~/bin/
$ ls -l git-remote-hg 
-rwxr-xr-x  1 andy  andy  35844  9 Dec 13:56 git-remote-hg

from git-remote-hg.

OK, another case that would match your symptoms: the interpreter for git-remote-hg cannot be found.

Example:

> which git-remote-hg
/home/bpierre/progs/bin/git-remote-hg
> head /home/bpierre/progs/bin/git-remote-hg
#!/usr/bin/python_bad_version

print 'arst'
> git clone "hg::http://selenic.com/repo/hello"
16:25:11> git clone "hg::http://selenic.com/repo/hello"
Cloning into 'hello'...
fatal: Unable to find remote helper for 'hg'

So check it's the correct Python version.

from git-remote-hg.

Hmm, I think the interpreter is ok:

$ head git-remote-hg
#!/usr/bin/env python2
#
# Copyright (c) 2012 Felipe Contreras
#

# Inspired by Rocco Rutte's hg-fast-export

# Just copy to your ~/bin, or anywhere in your $PATH.
# Then you can clone with:
# git clone hg::/path/to/mercurial/repo/

~/bin/
$ /usr/bin/env python2 --version
Python 2.7.8

One weirdness though is which doesn't find the script.

~/bin/
$ which git-remote-hg 
(nothing)

I can see how this would mean git can't find the remote helper.

However I have no idea why which can't see git-remote-hg.

from git-remote-hg.

Yeah, which not finding it is weird. What happen if you call git-remote-hg directly? It should error out with: "ERROR: Not enough arguments.".

from git-remote-hg.

Yes, it does:

$ ./git-remote-hg 
ERROR: Not enough arguments.

So I guess git-remote-hg is fine...the problem is somewhere else at my end.

from git-remote-hg.

The problem's definitely not with git-remote-hg. I realised that other executables in my ~/bin directory weren't visible to which even though I could execute them.

My PATH starts with .git/safe/../../bin:. This is so that I can run known-safe project executables easily. However it seems to break which's search since removing it makes all of my ~/bin directory, including git-remote-hg visible to which again.

Sorry for the noise and thank you for your help!

from git-remote-hg.

I notice you're calling it with a relative path, does it work without it? Are you sure your PATH is correctly set?

Also you could try this:

> git --exec-path="$HOME/bin:$(git --exec-path)" clone "hg::http://selenic.com/repo/hello"

from git-remote-hg.

I can execute git-remote-hg from anywhere and I get ERROR: Not enough arguments. At the same time which git-remote-hg can't see it.

My PATH starts with the entry I described above, which is a location which only exists in certain directories. I wonder whether which gives up if the first location in PATH doesn't exist.

I tried git --exec-path... and it went further than before...before crashing:

$ git --exec-path="$HOME/bin:$(git --exec-path)" clone "hg::http://selenic.com/repo/hello"
Cloning into 'hello'...

This last error is due to incompatible changes to the Mercurial API in the last version, you need this patch: https://github.com/felipec/git-remote-hg/pull/28/files

from git-remote-hg.

Thanks, that patch worked for me.
