Python Certbot 模块“集合”没有属性“映射”

Question

当我尝试在 Linux Ubuntu Server 20.04.3 LTS 上的控制台中运行

certbot

时，出现以下错误：

Traceback (most recent call last):
  File "/usr/bin/certbot", line 11, in <module>
    load_entry_point('certbot==0.40.0', 'console_scripts', 'certbot')()

    class PluginsRegistry(collections.Mapping):
AttributeError: module 'collections' has no attribute 'Mapping'

我已经寻找解决方案，但还没有找到。即使有相同错误的帖子也无法解决我的问题。奇怪的是，大约两个月前它就起作用了。

我正在运行 Python 3.10。

Answer 1

就我而言，我编辑了文件

/usr/bin/certbot

并将

#!/usr/bin/python3

更改为：

#!/usr/bin/python3.8

，因为Certbot尚不支持Python 3.10

Answer 2

请尝试这个：

sudo python3 -m venv /opt/certbot/
sudo /opt/certbot/bin/pip install --upgrade pip
sudo /opt/certbot/bin/pip install certbot certbot-nginx
sudo ln -s /opt/certbot/bin/certbot /usr/bin/certbo
