Python 3.x 卸载python3后系统出现故障

我使用Parrot OS v4.7，Pyinstaller出现问题（依赖项问题，但所有依赖项都已满足/安装），因此我在谷歌上搜索并尝试卸载和重新安装Python3

我跑

但它也开始删除其他软件包， 现在电脑不能正常工作了

它删除了：

• 配合界面
• 蓝鱼

屏幕截图不起作用，它说：

Failed to execute child process “mate-screenshot” (No   such file or directory))

• 仪表板
  

• 和其他许多软件包一样，该系统的功能与以前不同

现在，当我试图重新安装Python3以恢复它们时，出现了错误。 它在运行时提供以下输出

当我跑的时候

apt-get install python3

或

我得到：

请帮助我重新安装Python3并取回已删除的软件包，以便计算机可以正常工作

大多数情况下，它删除了系统包。

已经完成了。除非您能够从头开始构建linux，否则无法让它正常工作：）

---

重新安装是最快的方法

我有相同操作系统的可引导USB，所以有可能从那里加载损坏或丢失的软件包吗。。。？我认为从头开始构建linux没有那么容易…@CHD不，不要重建。简单地

apt get install mate interface

和其他相关软件包，他们将重新安装python3。你必须和python一起生活。。。

apt-get install --reinstall python3
