各种命令中出现“ModuleNotFoundError：没有名为‘apt_pkg’的模块”

我在各种情况下都会收到以下错误，例如当我尝试启动未安装的包时：

   $ tldr
    Traceback (most recent call last):
      File "/usr/lib/command-not-found", line 28, in <module>
        from CommandNotFound import CommandNotFound
      File "/usr/lib/python3/dist-packages/CommandNotFound/CommandNotFound.py", line 19, in <module>
        from CommandNotFound.db.db import SqliteDatabase
      File "/usr/lib/python3/dist-packages/CommandNotFound/db/db.py", line 5, in <module>

    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'
Error in sys.excepthook:

  File "/usr/lib/python3/dist-packages/apport_python_hook.py", line 63, in apport_excepthook
    from apport.fileutils import likely_packaged, get_recent_crashes
  File "/usr/lib/python3/dist-packages/apport/__init__.py", line 5, in <module>
    from apport.report import Report

    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/lib/command-not-found", line 28, in <module>
    from CommandNotFound import CommandNotFound
  File "/usr/lib/python3/dist-packages/CommandNotFound/CommandNotFound.py", line 19, in <module>

    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

我已经尝试过解决方案ModuleNotFoundError：没有名为“apt_pkg”的模块但这没用。我还尝试安装并重新安装不同版本的 python，并更改 update-alternatives 链接。我怀疑我以某种方式破坏了操作系统使用的 python 的配置。

一些一般信息：

$ cat /etc/os-release
NAME="KDE neon"
VERSION="5.18"
ID=neon
ID_LIKE="ubuntu debian"
PRETTY_NAME="KDE neon User Edition 5.18"
VARIANT="User Edition"
VERSION_ID="18.04"
HOME_URL="http://neon.kde.org/"
SUPPORT_URL="http://neon.kde.org/"
BUG_REPORT_URL="http://bugs.kde.org/"
LOGO=start-here-kde-neon
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=bionic
UBUNTU_CODENAME=bionic

python2：

$ update-alternative s --config python
    There is only one alternative in link group python (providing /usr/bin/python): /usr/bin/python2.7
    Nothing to configure.

$ python --version
Python 2.7.17

python3：

$ update-alternatives --config python3
There is only one alternative in link group python3 (providing /usr/bin/python3): /usr/bin/python3.7
Nothing to configure.

$ python3 --version
Python 3.7.5

确保已安装 python-apt。您可以删除并重新安装 python3-apt。尝试：

sudo apt install python3-apt --fix-missing

或者

sudo apt remove python3-apt
sudo apt autoremove
sudo apt autoclean
sudo apt install python3-apt

也许下面的代码比以前的删除 python3-apt 更好

sudo apt remove --purge python3-apt

您可以使用 apt-get 代替 apt。希望这对您有帮助。
