如在参考的作者所述，其实出现ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.,并不是都是搜索这个找到相关的解决办法。
最主要的还是自己从这个错误日志里找到解决办法。
比如： 我这里，找到第一个ERROR的提示是：ERROR: Could not find a version that satisfies the requirement setuptools_scm (from versions: none)
那就是少了setuptools_scm这个工具包，那使用代码
pip install setuptools_scm
就可以解决问题了。不然的话，再加上这个命令看看怎样：pip install -r requirements.txt
