How can I edit PYTHONPATH on a Mac?
提问by James
How can I permanently change the PYTHONPATH on a mac? I've tried editing .bash_profile, but when I use print sys.pathin a file it gives a huge list of different URLs than the .bash_profile. In Terminal when I type echo $PYTHONPATHit shows a blank line. I don't want to use sys.path.append('...') because then I have to put that in every file.
如何在 Mac 上永久更改 PYTHONPATH？我试过编辑 .bash_profile，但是当我print sys.path在文件中使用它时，它提供了一个与 .bash_profile 不同的 URL 列表。在终端中，当我输入时，echo $PYTHONPATH它显示一个空行。我不想使用 sys.path.append('...') 因为那样我必须把它放在每个文件中。

You can append the path to
$PATHand not to$PYTHONPATH.if you insist to change the
PYTHONPATH, in some context that is prefferable:do this:
export PYTHONPATH=$PYTHONPATH:/Users/username/pymodules- To make sure you are following the convention of what to append to
PYTHONPATHsee What exactly should be set in PYTHONPATH?.
您可以将路径附加到 ，
$PATH而不是附加到$PYTHONPATH。如果您坚持更改
PYTHONPATH, 在某些情况下是可取的：做此：
export PYTHONPATH=$PYTHONPATH:/Users/username/pymodules- 为了确保您遵循附加内容的约定，以
PYTHONPATH查看 PYTHONPATH 中究竟应该设置什么？.
