certbot 无法从“urllib3.contrib”导入名称“appengine”

Question

在我的 Ubuntu 22.04.2 LTS 和 Python 3.10.6 上，Certbot 给出以下错误：

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/requests_toolbelt/_compat.py", line 48, in <module>
    from requests.packages.urllib3.contrib import appengine as gaecontrib
ImportError: cannot import name 'appengine' from 'requests.packages.urllib3.contrib' (/usr/local/lib/python3.10/dist-packages/urllib3/contrib/__init__.py)

带有完整的错误消息：

During handling of the above exception, another exception occurred:

    sys.exit(load_entry_point('certbot==1.21.0', 'console_scripts', 'certbot')())

ImportError: cannot import name 'appengine' from 'urllib3.contrib' (/usr/local/lib/python3.10/dist-packages/urllib3/contrib/__init__.py)

这是很多错误，我不知道从哪里开始解决它。我将不胜感激！

Answer 1

urllib3 由 apt 和 pip 安装。我通过发出以下命令删除了 pip 版本：

pip3 uninstall urllib3

现在 certbot 工作正常。
