如何删除PIP安装的所有软件包? [英] How do I remove all packages installed by PIP?

问题描述

我想将我的Python安装恢复到其基本状态，以便可以开始使用virtualenv.是否有一种简单的方法可以只卸载那些在设置了Python之后安装的软件包?

I want to revert my Python install back to its base state so I can start using virtualenv. Is there an easy way to uninstall only those packages that have been installed after Python was set up?

推荐答案

以下命令应该可以解决问题:

The following command should do the trick:

pip freeze > requirements.txt && pip uninstall -r requirements.txt -y

或者，您可以跳过任何中间文件(即requirements.txt)的创建:

Alternatively you can skip the creation of any intermediate files (i.e. requirements.txt):

pip uninstall -y -r <(pip freeze)
