How to permanently append a path to Python for Linux?

Question

I know there are multiple solutions online, but some are for windows, some are environmental variable, etc..

What is the best way?

Answer 1

Find your site-packages directory and create a new file called myproj.pth

Inside that file, put each directory you want to add, one per line like so:

/home/myuser/svn-repos/myproject
/home/myuser/svn-repos/SomeOtherProject

Python loads *.pth every time it runs, and imports all paths in each of those files.

In Ubuntu, that directory can often be found at /usr/local/lib/python2.6/dist-packages/

Answer 2

I personally just define PYTHONPATH in ~/.bashrc, as for what's the "best" approach? I think that's hard to answer (or rather, there's no correct answer). It depends.
