ImportError：无法从“六个”导入名称“ ensure_str”

问题描述

当我尝试安装netfilterqueue时出现此错误。 甚至我无法使用pip卸载/检查/安装。
然后我搜索了stackoverflow，并说了其中一个用法：

sudo pip install -U setuptools

再次出现此错误。

  Traceback (most recent call last):

    ImportError: cannot import name 'ensure_str' from 'six' (/usr/lib/python3.8/site-packages/six.py)

谢谢。

解决方法

我能够通过将 Six.py 从 复制到 /usr/lib/python3.8/six.py 中来完成这项工作……您需要 sudo 来创建或更新此文件。
