Package ‘importlib-metadata‘ requires a different Python: 3.6.10 not in ‘＞=3.7‘

报错

 ERROR: Package 'importlib-metadata' requires a different Python: 3.6.10 not in '>=3.7'
 WARNING: You are using pip version 20.0.2; however, version 21.3.1 is available.
 You should consider upgrading via the '/usr/local/bin/python -m pip install --upgrade pip' command.

原因

importlib-metadata如果不指定版本会默认安装最新的，要求依赖的Python版本>=3.7 ，但项目使用的Python==3.6.10

解决

指定importlib-metadata满足Python 3.6.10 的版本，所以在reqiurements.tex中添加

importlib-metadata==4.0.1

重新安装项目依赖
