ImportError: No module named mercurial

[thomaslevesque]

I get an error trying to clone a repo with git-remote-hg on Raspbian:

pi@raspberrypi ~/sources $ git clone hg::https://code.google.com/p/markdownsharpCloning into 'markdownsharp'...
Traceback (most recent call last):
  File "/home/pi/bin/git-remote-hg", line 15, in <module>
    from mercurial import hg, ui, bookmarks, context, encoding
ImportError: No module named mercurial

From what I understand, I need to install the mercurial Python module. I tried to install it with easy_install, but I got some errors:

Sorry if it's a basic question, I don't know much about Python and Linux...

Mercurial uses Python version 2, not 3, so try again with easy_install-2.7 (or equivalent for you Python version).

Thanks!

I only had easy_install-pypy available, so I had to install easy_install-2.7. Then I also had to install python-dev to be able to install mercurial. Then I had to use this patched version of git-remote-hg to be able to clone, due to #27
