正确的答案是 @arogachev的那个.

如果要更改virtualenv中使用的PYTHONPATH，可以将以下行添加到virtualenv的bin/activate文件中:

If you want to change the PYTHONPATH used in a virtualenv, you can add the following line to your virtualenv's bin/activate file:

export PYTHONPATH="/the/path/you/want"

这样，每次使用此virtualenv时都会设置新的PYTHONPATH.

This way, the new PYTHONPATH will be set each time you use this virtualenv.

(回答@RamRachum的评论)

要将其恢复到deactivate上的原始值，可以添加

To have it restored to its original value on deactivate, you could add

export OLD_PYTHONPATH="$PYTHONPATH"

在前面提到的行之前，然后将以下行添加到您的bin/postdeactivate脚本中.

before the previously mentioned line, and add the following line to your bin/postdeactivate script.

export PYTHONPATH="$OLD_PYTHONPATH"
