OSX Permanently Set PYTHONPATH

Question

I have a problem where my PYTHONPATH variable always has a blank value. I can fix it temporarily like this: export PYTHONPATH=$(python -c 'import sys;print ":".join(sys.path)') but is there a more permanent way to do this?

Answer 1

You could put that line in your ~/.bash_profile file, at which point it is run each time a new terminal is opened. (See here for more about this file).

Answer 2

1. put the path setting in /etc/profile, it will impact to all users.
2. put the path in your home directory ~/.profile, ~/.bashrc, ~/kshrc (depand on your shell).
