什么原因会导致Python中缺少"gi"模块？

Question

在Ubuntu中对默认的Python版本进行了一些不太聪明的编辑，从2.7改为3.2，结果导致整个系统崩溃。当我的电脑爆炸并且一切停止工作后，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中的默认版本改回2.7），但仍然有一些问题没有解决。

例如，当我在Python解释器中输入import gi时，会出现以下消息：

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

一些程序也会出现错误（例如：gnome tweak tool）。我尝试过从软件中心和源代码重新安装Python，但是仍然出现相同的错误。

现在，python --version返回：

 Python 2.7.2

还有一些依赖于Python 2.7的软件包现在可以正常工作（例如软件中心），但仍然存在一些问题。有没有办法完全重新安装Python 2.7作为默认版本？

你尝试过重新安装python-gobjects吗？ - Javier Rivera

我做了，但它重新安装了"python-gobject 3.0.0-0ubuntu4"。这是2.7的正确版本号吗？ - Colin Dumitru

是的。它是我系统上安装的，并且正常工作。 - Javier Rivera

你尝试过重新配置Python吗？例如：sudo dpkg-reconfigure python2.7？ - sagarchalise

是的，但是同样的错误仍然存在。 - Colin Dumitru

对于那些手动升级到Python 3.7的用户，你只需要编辑/usr/bin/gnome-tweaks文件，并将#!/usr/bin/python3更改为#!/usr/bin/python3.6。在此之后，一切应该正常运行，就像魔术般顺利。 - Aris

尝试运行sudo ibus-setup。说不定会有用的！ - Milan

Answer 1

我找到了三种方法来做这个：

1. 简单的方法：

   sudo apt install python3-gi
   

2. 适用于虚拟环境用户的vext方式：

   pip install vext
   pip install vext.gi
   

3. 纯Python开发者的方式：

   安装一些开发工具：

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

   安装Python包：

   pip install PyGObject

在这种情况下，软件包是共享的 - 所以适用于两者。已经移除了对Debian的引用，以避免混淆。 - Matthew

注意：如果你安装了"python3-dev"，它可能会升级你已经安装的python3，并且可能会给你带来麻烦，就像之前发生在我身上的那样。 - Doğuş

在我的虚拟环境中安装vext包只是将错误更改为“ImportError：无法从'gi'（/usr/lib/python3/dist-packages/gi/init.py）导入名称'_gi'”。 - Cerin

Answer 2

如果您已经安装了Anaconda并将其设置为默认的Python环境，可以通过以下方式安装gi模块：

conda install -c conda-forge pygobject 

也请参阅： https://bugs.launchpad.net/ubuntu/+source/ibus/+bug/1611523

在这里找到了一个小的解决办法here，对我起了作用。

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

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

- Pierre de LESPINAY

这个方法解决了我在Arch Linux上的问题！另外一个解决方案是由Jeremy Bicha提供的，在Arch Linux上安装python-gobject（或者在Ubuntu上安装python3-gi），但对我来说没有起作用！ - ArchLinuxTux

Answer 4

在终端中运行以下命令：

sudo apt install python3-gi

如果你需要Python2的支持，可以使用以下方法：

sudo apt install python-gi

- Jeremy Bicha

Answer 5

sudo apt-get install -y python-gobject

在Ubuntu 18.04上为我修复了这个问题。

Answer 6

在我的情况下：

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

所以你需要检查的是你是否有那个文件可用。如果没有，那就检查一下 /usr/lib/python2.7/dist-packages/gi/__init__.py 是否指向 /usr/share/pyshared/gi/__init__.py。你应该有那个文件，因为你有 python-gobject 3.0.0-0ubuntu4（是的，我也有完全相同的版本）。

如果 gi 包存在，那么你应该查看一下你的 sys.path 输出。如果 /usr/lib/python2.7/dist-packages 没有包含在内，那就添加进去然后再试一次。

一旦导入成功，你可以设置你的 PYTHONPATH 或者进一步调查路径设置不正确的原因。

待处理的问题可能是你的 `site.py` 文件无效，可能是由于某种原因，或者更有可能的是，你没有获取到正确的 `site.py` 文件（它应该位于 `/usr/lib/python2.7/` 下）。在这种情况下，查看here以回顾 Python 用来查找该文件的所有目录，并检查你的环境是否正确。

增加解释器的冗长度对于解决这个问题有很大帮助。即使经过了这一切，我尝试将2.7版本的dist-package简单地符号链接到我的usr/local 3.x版本的dist-package，虽然进展了一点，但并不多。

 sudo ln -s /usr/lib/python2.7/dist-packages/gi/ /usr/local/lib/python3.2/dist-packages
~$ python3
Python 3.2.2+ (default, Feb 16 2012, 19:05:44) 
[GCC 4.6.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gi
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/lib/python3.2/dist-packages/gi/__init__.py", line 23, in 
    from ._gi import _API, Repository
ImportError: /usr/lib/libpyglib-gi-2.0-python2.7.so.0: undefined symbol: _Py_ZeroStruct

如果你能找到那个丢失的符号，你可能能够解决这个问题。这是导致我走到这一步的冗长导入输出。此外，这似乎与之相关：http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=645963，祝你好运。

在Python环境中，一切都与依赖关系有关，就像在C语言中一样。但是，如果你通过PyPI（pip）或系统打包工具（apt、yum、brew等）安装模块，这将影响所有Python脚本的进一步调用方式。 例如，安装PyGObject。

A.（选择其中一个）通过软件包工具（在某些情况下可能无法正常工作，apt可能被禁用或Python版本发生变化）：

    sudo apt install python3-gi python3-gi-cairo gir1.2-gtk-3.0

或者B.（选择其中一个）通过PyPi（这应该总是有效的）

    cat <<EOF | tee requirements.txt
    pycairo
    PyGObject
    EOF
    pip3 install -r requirements.txt 

A. Python库通过常见的软件包工具进行安装，如果不使用标准的python3-软件包，进一步更新将会破坏依赖系统。

    python3
    >>> import gi.repository

B.（推荐给开发者）Python模块可能会安装在虚拟环境中（virtualenv create /usr/src/venv）。因此，它将在启用了virtualenv的shell块中找到：

    source /usr/src/venv/bin/activate
    pip3 install -r requirements.txt
    python3
    >>> import gi.repository

requirements.txt 包含了你想要添加到 PYTHONPATH 的 Python 模块列表。 virtualenv 确保每个所需的模块都可以从所需的 Python 版本和库中使用，并且优先于系统软件包工具管理器。

在我的情况下，我一直使用的是Python3.6，最近升级到了Python3.7，然后出现了这个问题。以下解决方案适用于我：

cd /usr/lib/python3/dist-packages/gi
sudo ln -s _gi.cpython-{36m,37m}-x86_64-linux-gnu.so

这个方法在Ubuntu 20.04、Python 3.8和虚拟环境下对我有效。

为了方便起见，我引用如下：

..但是我意识到我的Python版本是3.6，而gi安装在Python 3目录下，因为我是通过这个命令"sudo apt-get install python3-gi"来安装的，所以我在终端上运行了这个命令：

ln -s /usr/lib/python3/dist-packages/gi /home/your_name_goes_here/miniconda3/lib/python3.6/site-packages/

(附注：在"your_user_goes_here"中，你要填入你的用户名)

实际上，为了正确性（因为我不使用conda），我修改了这个命令为：

$ ln -s /usr/lib/python3/dist-packages/gi /home/your_name_goes_here/your_python_path/3.8/lib/python3.8/site-packages
