删除 pip 安装的所有软件包的最简单方法是什么? [英] What is the easiest way to remove all packages installed by pip?

问题描述

我正在尝试修复我的一个 virtualenv - 我想将所有已安装的库重置回与生产匹配的库.

I'm trying to fix up one of my virtualenvs - I'd like to reset all of the installed libraries back to the ones that match production.

是否有使用 pip 执行此操作的快速简便的方法?

Is there a quick and easy way to do this with pip?

推荐答案

我发现这个片段是一个替代解决方案.与重新制作 virtualenv 相比，移除库更优雅:

I've found this snippet as an alternative solution. It's a more graceful removal of libraries than remaking the virtualenv:

pip freeze | xargs pip uninstall -y

如果您通过 VCS 安装了软件包，则需要排除这些行并手动删除软件包(从下面的评论中提升):

In case you have packages installed via VCS, you need to exclude those lines and remove the packages manually (elevated from the comments below):

pip freeze | grep -v "^-e" | xargs pip uninstall -y
