python - ModuleNotFoundError 没有名为 apt_pkg 的模块

Question

我正在尝试使用命令添加一个 repo

 sudo add-apt-repository ppa:gezakovacs/ppa

以下是完整的错误-

    Traceback (most recent call last):
File "/usr/bin/add-apt-repository", line 11, in <module> from softwareproperties.SoftwareProperties import SoftwareProperties, shortcut_handler
File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 27, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'
Error in sys.excepthook:

    import apt
File "/usr/lib/python3/dist-packages/apt/__init__.py", line 23, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

Original exception was:
Traceback (most recent call last):
File "/usr/bin/add-apt-repository", line 11, in <module> from softwareproperties.SoftwareProperties import SoftwareProperties, shortcut_handler
File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 27, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

遇到上述错误。

我已经在 Xubuntu 16.04 上安装了 python2、Python3.5 和 Python3.6。它会导致任何问题吗？？？

这可能是因为您以一种奇怪的方式切换了 Python 版本。你有 /usr/lib/python3/dist-packages/apt_pkg.so 吗？如果您删除了 python 版本，这可能会丢失。

对我有用的答案来自 askubuntu forums :

ln -s /usr/lib/python3/dist-packages/apt_pkg.cpython-36m-x86_64-linux-gnu.so /usr/lib/python3/dist-packages/apt_pkg.so
