如何将 virtualenv 与本地 dist 包隔离? [英] how to isolate virtualenv from local dist-packages?

问题描述

如何使用/usr/local/lib/python2.7/dist-packages"停止 virtualenv?

How do you stop virtualenv using '/usr/local/lib/python2.7/dist-packages'?

目前我运行时它

virtualenv --no-site-packages ENV

它仍然使用我希望停止的 dist-packages

it still uses the dist-packages that i wish to stop

/usr/local/lib/python2.7/dist-packages 在 PYTHONPATH 中，其他应用程序需要在那里

/usr/local/lib/python2.7/dist-packages is in the PYTHONPATH, it needs to be there for other apps

推荐答案

您的编辑解释了您正在观察的行为.

Your edit explains the behaviour you are observing.

您需要在激活 virtualenv 时取消设置 PYTHONPATH.

You need to unset PYTHONPATH when activating the virtualenv.

unset PYTHONPATH
source /path/to/virtualenv/bin/activate

virtualenv --no-site-packages ENV 创建一个空的 virtualenv 就好了，但是您的 PYTHONPATH 导出会使您的空 virtualenv 无效.

virtualenv --no-site-packages ENV creates an empty virtualenv just fine, but your PYTHONPATH export nullifies your empty virtualenv.

为了使事情更简单，您可以编辑 activate 脚本并在那里添加 unset PYTHONPATH 命令.如果您想在停用 virtualenv 后恢复原始 PYTHONPATH，您还需要修改该文件中的 deactivate 函数.

In order to make things simpler you can just edit the activate script and add the unset PYTHONPATH command there. If you want to restore the original PYTHONPATH upon deactivating the virtualenv you also need to modify the deactivate function in that file.
