virtualenv has a very different usage than sitecustomize.
Basically, virtualenv can be used as a sandbox for installing python
packages, whereas sitecustomize.py is just a python script imported by the
python interpreter upon startup (
https://docs.python.org/2/library/site.html ).
One possible workflow:
- startup a new virtualenv, using mayapy as the python interpreter
(- patch the virtualenv activate script file to load the corresponding
libpython* dynamic library files (mayapy has some harcoded path coming from
autodesk build))
(-install python devel headers to be able to compile python binary modules)
- "pip install" the 3rd party packages you need
- create a sitecustomize.py containing a call to
site.addsitedir('/path/to/mayapy_virtualenv/.../site-packages')
- put this file in the maya site-packages installation dir or change the
PYTHONPATH environment variable before launching maya.bin/mayapy/mayabatch
If you set directly PYTHONPATH to
'/path/to/mayapy/virtualenv/site-packages', it won't be processed correctly
(.pth file won't be loaded)
I hope this helps, I don't quite understand what you mean by "maya-python"
so perhaps I'm missing something.
