python - 在具有多个 python 版本的 Ubuntu 18.04 中卸载所有 Python 包

Question

当我键入python并点击选项卡时，将显示以下包

python             python3            python3.6m         python3m
python2            python3.6          python3.6m-config  python3m-config
python2.7          python3.6-config   python3-config

当我键入pip list以下包时，会显示

我想删除所有的包，但保留那些对操作系统很重要的包

Answer 1

如果我创建一个 ubuntu 18.04 容器，并安装 python、python3 并做一个 pip 列表，这些就是我得到的包。所以理论上，你可以删除除这些包之外的所有包：

$ docker run -it --rm ubuntu:18.04 bash

# inside the docker container:

$ apt update
$ apt install python python-pip  python3 python3-pip
$ pip list
