How can I insert new modules in PYTHONPATH?

Question

I'm installing http://bitbucket.org/agr/ropemacs for my emacs.

In README.txt it say:

Note that rope and ropemacs should be in your PYTHONPATH for this to work.

I check my sys.path python, but there is't any ropemacs there! but I have installed it! how can I instert ropemacs in PYTHONPATH?

Answer 1

If you ran the included setup.py, then the package should be correctly installed and all is well, you can checky by importing it, open a python prompt and type import ropemacs.

You probably wouldn't see a directory just for this package, because setuptools normally installs python packages in your site-packages directory, which on my machine is in /usr/lib/python2.7/site-packages and C:\Python27\Lib\site-packages, for the obvious platforms.

Answer 2

PYTHONPATH is an environment variable. You can add directories to it with a command like

PYTHONPATH="$PYTHONPATH:/path/to/rope:/path/to/ropemacs"

That can be done from the command line before running emacs, or more permanently in your ~/.bashrc or ~/.profile. There might be a more convenient emacs-specific way to do it but I am a vim fiend so I can't help you with that.
