I’m trying to install TortoiseHg for Mac following these instructions : https://bitbucket.org/tortoisehg/thg/wiki/developers/MacOSX#!alternative-install-via-macports

I’m trying to follow the instructions about the “Alternative: Install via Homebrew” and I have an issue.

When I execute ./thg log as in the instructions it works, TortoiseHg is launching. However when I try to create an App from the python script, the App is created but when I launch it it crashes.

Here is the output :

Traceback (most recent call last):
  File "/Users/fabienhenon/Documents/thg-mac-app/dist/TortoiseHg.app/Contents/Resources/__boot__.py", line 316, in <module>
    _run()

When I type : hg --version I have the following output :

Mercurial Distributed SCM (version 2.4.2+20130102)

    I’ve found a solution to solve this issue.

    From the error message I had, the script could not find the module named mercurial. I’m new with Python so I had to make some researches to know how module importation works and I found something about dynamically importing a module using the 'sys' module.

    My solution was to edit the tortoisehg source code (the file where the error came from) to dynamically add the path to my mercurial module to the 'sys.path' so that the program knows where to find the mercurial module.

    Here is the code (in the ‘thg’ python file, line 56 (as mentioned by the error)) :

    import sys
sys.path.append("/Library/Python/2.7/site-packages")

    You have to add this code just before this line :

    from mercurial import demandimport

    And the path must correspond to the location of your mercurial folder.
