Answer 1

@RaminNietzsche，几天后我找到了解决这个问题的方法，手动安装的是setuptools_scm，我不知道为什么pip没有找到任何合适的发行版作为错误消息说。

我做的是：

pip install setuptools_scm

Answer 2

再看一下OSError：Name or service not known。

这意味着您的全新安装尚未安装适当的解析程序。几天后可能会自行修复，因为你修复了你的解析器。

Answer 3

就我而言，我看到以下错误：

Could not find suitable distribution for Requirement.parse('setuptools_scm<4,>=3.2')

我尝试运行 pip install setuptools_scm 但它不起作用，因为已经安装了包。

对我有用的是安装 setuptools_scm 要求的确切版本。

pip install setuptools_scm==3.2
