删除了 python 二进制文件，并且无法使用 apt-get 恢复，我该怎么办？

Question

嗯。是的。我想重新开始，因为我对依赖关系感到困惑，所以我运行了“whereis python”，然后删除了出现的所有文件和目录。然后当我运行 apt-get install python 时，我当然会收到很多错误。有没有办法在 ubuntu 上重新安装 python，而不是直接进行彻底清除？

以下是尝试安装 python 二进制文件的输出：

root@ubuntu14-server:/home/kpoole# apt-get install python

python is already the newest version.

Answer 1

以后不要再这样做了。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（除非它们明确为此设置，如配置文件等）。

话虽如此，如果您无法（看起来可能是这种情况）用来apt-get从这种情况中恢复，因为有些部分过程需要 python 已经安装，那么您有几个选择（并非所有选择都一定有效）。

您可以手动获取 python（及相关）.deb文件并尝试使用dpkg手动安装它们（您需要手动解决依赖顺序以确保其正常工作）。类似于：

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。

此后，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，但通常它会要求sudo dpkg --configure -a。sudo apt-get -f install可以根据情况提供帮助。

您可能还可以使用安装媒体恢复模式（或重新安装）来修复此问题。

Answer 2

打开终端并输入以下命令：

第一次尝试

sudo apt-get -f install 

如果不起作用，请尝试

sudo dpkg --configure -a 

如果仍有问题，请运行

sudo apt-get install --reinstall python python-chardet python-colorama python-distlib python-django python-django-tables2 python-six python-html5lib python-lxml python-minimal python-pkg-resources python-setuptools python-urllib3 python-requests python-pip python-virtualenv

作为最后的手段，您可能需要使用以下命令删除这些软件包，然后使用上述命令重新安装这些软件包。如果是这种情况，您需要非常仔细地观察。使用以下命令将会出现一个卸载软件包的列表。您需要复制此列表并将其粘贴到 gedit 中。打开 gedit 并将软件包列表粘贴到 gedit 中，按ctrl+h并输入 \n，然后在“搜索”中输入两个空格，在“替换为”中输入一个空格，以删除所有段落和多余的空格，然后单击“全部替换”，以便您的列表包含仅由单个空格分隔的软件包列表。

sudo apt-get purge python-chardet python-colorama python-distlib python-django python-django-tables2 python-six python-html5lib python-lxml python-minimal python-pkg-resources python-setuptools python-urllib3 python-requests python-pip python-virtualenv

最后，运行：sudo apt-get install并粘贴来自 gedit 的软件包列表以重新安装所有内容。

Answer 3

您应该删除每个给您带来困难的软件包，然后重新安装它们。

看https://askubuntu.com/a/32899/176376进行删除而不删除依赖项。

sudo dpkg -r --force-depends "package"

sudo apt-get install "package"

您应该先删除所有有问题的，然后重新安装它们。

sudo apt-get install -f每隔sudo dpkg --configure -a几个命令运行一次。

Answer 4

这是预期的行为。删除文件与卸载包或程序不同。

您已从安装中删除了所有与 Python 相关的内容，但您的包管理器不知道这一点。当您再次安装 Python 时，apt 认为所有这些文件仍然存在，因此不会费心尝试重新下载它们。就 apt 而言，所有 Python 仍处于安装状态；您从未告诉过它其他情况。

您可以尝试以下方法来尝试纠正此问题：
sudo apt-get install --reinstall python

将来，使用apt-get remove或apt-get purge以图形方式从 Ubuntu 软件中心卸载软件包。
