如何在Mac上编辑PYTHONPATH? [英] How can I edit PYTHONPATH on a Mac?

问题描述

如何在Mac上永久更改PYTHONPATH?我尝试编辑.bash_profile，但是当我在文件中使用print sys.path时，它会提供比.bash_profile更大的不同URL列表.在终端中，当我键入echo $PYTHONPATH时，它会显示一个空行.我不想使用sys.path.append('...')，因为那样我就必须将它放在每个文件中.

How can I permanently change the PYTHONPATH on a mac? I've tried editing .bash_profile, but when I use print sys.path in a file it gives a huge list of different URLs than the .bash_profile. In Terminal when I type echo $PYTHONPATH it shows a blank line. I don't want to use sys.path.append('...') because then I have to put that in every file.
