无法安装一些带有无效组名错误的pip软件包

问题描述

我正在使用OctoPi 0.17.0与Octoprint 1.4.2，Python 2.7.16和pip 20.2.2一起运行setuptools 44.1.1。

我无法使用浏览器或或命令行安装任何插件。错误始终是相同的，如下所示。

它也直接来自pip注册表中的其他软件包（例如unicornhat），但我能够从同一pip实例成功更新pip和setuptools。

~/oprint/bin/python2 -m pip --verbose install "https://github.com/gdombiak/OctoPrint-OctoPod/archive/master.zip"
