python - 导入错误 : cannot import name '_gi' from partially initialized module 'gi' (most likely due to a circular import)

Question

当我想切换到 python 3.8 时，看起来我已经破坏了我的 python 安装。使用 Ubuntu 18.04。尝试使用 gi ，给出以下错误:

$ python
Python 3.8.1 (default, Dec 31 2019, 18:42:42) 
[GCC 7.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
 >>> from gi.repository import GLib, Gio
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 42, in <module>
    from . import _gi
ImportError: cannot import name '_gi' from partially initialized module 'gi' (most likely due to a circular import) (/usr/lib/python3/dist-packages/gi/__init__.py)

尝试为 python 运行 update-alternatives，但它告诉我只配置了一个 python 替代方案(3.8)。

试图重新安装python3-gi和python3.8。还是同样的问题

Answer 1

安装 gi对于 python 3.8:python3.8 -m pip install pgi然后，而不是 import gi利用:

import pgi
pgi.install_as_gi()
from gi.repository import GLib, Gio

或者，您可以强制为 python 3.8 安装 PyGObject:
sudo python3.8 -m pip install --ignore-installed PyGObject
这应该允许一个 from gi import ...和以前一样。
