如何在 ubuntu 20.04 中安全地重新安装或修复 python3.8 并将其所有文件恢复为默认值？

我正在摆弄 python3 和 pip，一些软件包似乎损坏了一些 python 文件，当我尝试使用 pip 时，我收到了这个错误和其他一些错误：

Exception:

    status = self.run(options, args)

我尝试了几个小时使用相关问题上建议的方法，但都没有帮助

根据一些线程，您不应该删除 python3.8，因为许多系统资源都在使用它，那么我该如何修复它的所有文件并重新安装它？我希望它基本上恢复为默认值并删除所有已安装的软件包，我该怎么做？

您不必删除python3。这只会让事情变得更糟。相反，请pip按照以下命令删除并重新安装。

sudo apt remove python3-pip
sudo python3.8 -m easy_install pip
