尝试重新安装后损坏的 python 依赖项

Question

我在我的 ubuntu 18.04 系统上安装了几次 python，并尝试卸载所有必要的，然后正确地重新安装 python3.6

所以我删除了 下列出的所有文件夹，这whereis python可能是一个坏主意。

现在如果我运行sudo apt-get install python3.6它返回

我并不是一个真正有经验的 linux 用户，所以我被困在这里。有人知道如何修复我的 python 安装吗？

dpkg: 错误处理包python3.6-minimal (--configure):
dpkg: 错误处理包python3.6 (--configure):
dpkg: 错误处理包python3.6-dev (--configure):

您有 3 个 dpkg 包错误需要重新配置，接下来要做的一件事

sudo dpkg --configure -a

我看到你有 4 个包没有升级

确保所有软件包都已更新和升级，运行

sudo apt-get update && sudo apt-get upgrade && sudo apt-get autoremove

如果输出日志说

Errors were encountered while processing:  
python3.6-minimal  
python-minimal  
python3.6  
python3.6-dev

尝试打字 sudo apt-get install --fix-broken

如果在处理该包时仍然遇到错误，请尝试清除并删除所有 python 并重新安装它，请按照

sudo apt-get purge python* && sudo apt-get autoclean && sudo apt-get install python*

希望这可以帮助。
