I created some python hooks for Mercurial that use some external libraries (namely jira-python). In Linux, I install the packages using pip. In Windows, however, Mercurial comes with a bundled version of Python. My hooks fail when I run them because the external packages are not installed.
I want to make Mercurial / TortoiseHG use my Python installation so I can control its environment. How can I do that?
回答1:
You can install Mercurial package for Python:
- Mercurial 2.4 Python 2.7 package - x86 Windows
- Mercurial 2.4 Python 2.7 package - x64 Windows
For TortoiseHG-specific details I can suggest to inspect %TortoiseHg%\library.zip - it contains (some? all?) needed for TortoiseHG|Mercurial Python's modules, which list you can (try) to extend: "in Where is the Python path for TortoiseHG?" topic Steve Borho wrote:
TortoiseHg's entire python environment is contained within the library.zip that comes packaged with it.
What I suspect you can do is add a line or two to the top of your reviewboard extension file to add your installed python path to sys.path before trying to import simplejson
Hint for adding python path to sys.path is applicable for you too
Recommendation from Convert Extension page
you'll need to use a Mercurial installed on top of a stand-alone Python, and you may also need to do something like
set HG=python c:\Python25\Scripts\hgto override the default Win32 binaries if you have those installed also
回答2:
I have Mercurial installed through pip, and I also have TortoiseHg. My system path selects the Python version first.
I renamed C:\Program Files\TortoiseHg\hg.exe to something else, and then ran TortoiseHg. Everything still worked, but I haven't got a good way of verifying it does what you want. You can give it a shot.
