删除了python二进制文件，使用apt-get无法恢复，我该怎么办？

Question

好。是的。想要重新开始，因为我有依赖性混淆，所以我运行了“whereis python”并从字面上删除了所有出现的文件和目录。然后当我去运行 apt-get install python 时，我当然会遇到很多错误。有没有办法在 ubuntu 上重新安装 python 而不只是进行干净的擦拭？

这是尝试安装 python 二进制文件的输出：

python is already the newest version.
The following packages were automatically installed and are no longer required:
libexpat1-dev libpython-dev libpython2.7-dev
Use 'apt-get autoremove' to remove them.

以后不要这样做。不要手动删除（或以其他方式弄乱）通过包管理工具安装的任何文件（除非它们是明确设置的，如配置文件等）。

话虽如此，如果您无法（并且看起来可能是这种情况）用于apt-get从这种情况中恢复，因为该过程的某些部分预计已经安装了 python，那么您有几个选项（并非所有选项）一定会起作用）。

您可以.deb手动获取python（和相关）文件并尝试使用dpkg手动安装它们（您需要手动解析依赖顺序以确保它正常工作）。就像是：

apt-get download python2.7-minimal ## at least this package is necessary
sudo touch /usr/bin/python2.7 && sudo chmod +x /usr/bin/python2.7
sudo dpkg --unpack python2.7-minimal*

您应该检查其他丢失的二进制文件，例如pycompile，并应用相同的解决方案。

在此之后，建议检查 dpkg 数据库以查找未配置、半配置和刚解压的软件包：

sudo dpkg --check

阅读消息并应用修复程序，但通常它会要求sudo dpkg --configure -a. Ansudo apt-get -f install可以根据情况提供帮助。

您也可以使用安装介质恢复模式（或重新安装）来解决此问题。
