恢复 Python 安装

恢复 Python 安装

我使用的是 ubuntu precise。此版本上安装的 Python 版本是 2.7.6。但 Cloudera 需要 2.7.3。我只是按照。整个系统都无法运行。我甚至无法安装 jdk。我想要的是恢复此更改。我需要以某种方式恢复到默认的 2.7.6。

有什么建议么?

E: Sub-process /usr/bin/dpkg returned an error code (1)

sudo dpkg -C returns

 The following packages have been unpacked but not yet configured.
 They must be configured using dpkg --configure or the configure
  menu option in dselect for them to work:
 libgnome2-0:amd64    The GNOME library - runtime files
libgnome2-bin        The GNOME library - binary files
libgnome2-common     The GNOME library - common files
libgnomevfs2-0:amd64 GNOME Virtual File System (runtime libraries)
libgnomevfs2-common  GNOME Virtual File System (common files)

The following packages are only half configured, probably due to problems
configuring them the first time.  The configuration should be retried using
dpkg --configure <package> or the configure menu option in dselect:
gconf2               GNOME configuration database system (support tools)

如果我尝试重新配置,那么它就像一个循环错误。最后它指向 Python IO 模块错误

答案1

可能你在从 apt-get 重新安装 Python 时遇到了问题,因为 tarball 安装已经创建了 Python 中使用的文件

您可以下载 python 包及其依赖项,将所有文件放在同一目录中,然后使用 dpkg 安装并覆盖现有文件:

  1. 要获取 requeride 包,您只需运行apt-get install python即可获取 apt 要安装的包列表。

  2. 要下载它们,请apt-get download [paste here the list of the packages]在空文件夹中使用命令

  3. 要安装,请在同一文件夹中使用:dpkg --force-overwrite -i *.deb

我希望这个办法能奏效。祝你好运。

编辑:我的回答没有考虑到该编辑。您必须先修复 libgnome* 软件包中出现的问题,然后再尝试上述操作。

答案2

正如我在另一篇文章中看到的那样,您考虑重新安装 ubuntu,那么您可以尝试以下操作:

$ dpkg --list | grep -i python > ~/pythonpackages.txt
$ ### txt file just to review what was installed
$ sudo apt-get purge python*          #remove all python related packages
$ sudo rm -rf /var/lib/apt/lists      #remove apt information
$ sudo updatedb                       #refill the file location database
$ locate python                       #find all python related files
$ # remove all directories and files that you find with python
$ apt-get update
$ apt-get install python

注意:这不是彻底的清理或恢复,而是对与 Python 有关的任何内容进行更彻底的删除。因此,您可以重新尝试安装所有 Python 包。
