什么会导致python中缺少“gi”模块？

在Ubuntu中对默认Python版本进行了一些不那么聪明的编辑后，从2.7到3.2，我最终破坏了整个系统。 在我的计算机崩溃并且一切都停止工作后，我试图恢复我的更改（通过将/usr/bin/python2.7链接到/ usr / bin / python并将/ usr / share / python / debian_defaults中的默认版本更改回2.7）但有些事情仍然存在。

例如，当我在python解释器中键入“import gi”时，我收到以下消息：

>>> import gi Traceback (most recent call last): File "", line 1, in  ImportError: No module named gi >>> 

某些程序也会出现错误（例如：gnome tweak tool）。 我曾尝试从软件中心和来源重新安装python，但同样的错误仍然存​​在。

Python – 版本现在返回：

  Python 2.7.2 

还有一些依赖于python 2.7的软件包现在正在运行（例如软件中心），但有些东西仍然存在。 有什么办法可以完全重新安装python 2.7作为默认版本吗？

Answer 1

这里找到的解决方法对我有用：

 sudo nano /usr/bin/gnome-tweak-tool 

将#!/usr/bin/env python更改为#!/usr/bin/python

Answer 2

在终端中运行此命令：

 sudo apt install python3-gi 

或者如果您需要Python2支持：

 sudo apt install python-gi 

Answer 3

我发现了三种方法：

1. 简单的方法：

   sudo apt-get install python3-gi

   要么

2. 对于virtualenv用户 – vext方式

   pip install vext

   pip install vext.gi

3. 纯python开发方式：

   安装一堆开发人员的东西：

   sudo apt-get install pkg-config libcairo2-dev gcc python3-dev libgirepository1.0-dev

   安装python包：

   pip install gobject PyGObject

Answer 4

就我而言：

 >>> import gi >>> gi.__file__ '/usr/lib/python2.7/dist-packages/gi/__init__.pyc' 

那么你需要检查你是否有这个文件。 如果不是，则检查/usr/lib/python2.7/dist-packages/gi/__init__.py指向/usr/share/pyshared/gi/__init__.py 。 你应该拥有该文件，因为你有python-gobject 3.0.0-0ubuntu4 （是的，我有相同的版本）。

如果gi包在那里，那么你应该看一下你的sys.path输出。 如果未包含/usr/lib/python2.7/dist-packages ，则添加它/usr/lib/python2.7/dist-packages试。

导入后，您可以设置PYTHONPATH或进一步调查路径未正确设置的原因。

挂起的问题可能是你的site.py文件由于某种原因无效，或者更可能是你没有得到正确的site.py （它应该在/usr/lib/python2.7/下） 。 在这种情况下，请查看python用于查找该文件的所有目录，并检查您的环境是否正确。

Answer 5

增加解释器的冗长程度对于分解这个问题大有帮助。 即便在这之后，我尝试将2.7 dist-package的简单符号链接到我的usr / local 3.x dist-package并进一步了解，但不是很多。

  sudo ln -s /usr/lib/python2.7/dist-packages/gi/ /usr/local/lib/python3.2/dist-packages

 〜$ python3
 Python 3.2.2+（默认，2012年2月16日，19：05：44） 
 linux2上的[GCC 4.6.2]

如果您可以追踪丢失的符号，则可以解决此问题。 这是导致我这么远的所有详细的导入输出。 此外，这似乎相关： http ： //bugs.debian.org/cgi-bin/bugreport.cgi？bad = 645963 ，祝你好运。
