为了清除 WSL2 上的文件系统，我通过以下方式卸载了 python3
sudo rm -rf /usr/bin/python3
sudo rm -rf /usr/lib/python3
sudo rm -rf /usr/local/lib/python3
反过来，我很难通过 WSL 重新安装和使用 python3.*。当尝试通过 重新安装 python3 时sudo apt-get install --reinstall python3，出现了类似以下错误。

这让我陷入了几个我完全无法理解的困境。我按照类似的顺序执行了以下命令，然后才意识到我可能造成了更大的问题……

我试图理解这个问题的时间比我愿意承认的要长得多。关于这个问题的帖子也有很多，然而，这些讨论并不足以帮助我理解。
编辑：有人问我我的 Ubuntu 版本。我很想知道还有什么其他方法可以找到它，但是使用时lsb_release -a出现了以下错误。
-bash: /usr/bin/lsb_release: /usr/bin/python3: bad interpreter: No such file or directory
