    DEPRECATION: Uninstalling a distutils installed project (pyOpenSSL) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

有什么问题吗?

推荐答案

在系统范围的 Python 上安装库通常是个坏主意.为每个项目使用 virtualenv.

It's generally a bad idea to install libraries on your system-wide Python. Use a virtualenv for each project instead.
