可以安装本地Python软件包

Question

几乎没有系统升级后，我再也无法安装我的Python 3软件包了。这是输出：

    pab@pab:~/Mopiqtt-1.0.0 $ sudo pip3 install .

我正在努力，找不到解决方案。相关的包装版本：

pip                    22.1.1
setuptools             62.3.2
ez-setup               0.9

感谢您的任何帮助。

[edit}：如果我运行python3 stepup.py check相同的问题

我通过降级setuptools解决了这一问题：

pip3 install --force-reinstall setuptools==40.8.0

但是我对这个错误没有任何了解。
