pytest运行警告问题：DeprecationWarning: pkg_resources is deprecated as an API.

原因是setuptools版本问题

报错信息：DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
  from pkg_resources import iter_entry_points

1.首先查看自己的setuptools版本，终端运行pip show setuptools

2.卸载setuptools ,终端运行 pip uninstall setuptools

3.安装67.6.1版本  终端运行 pip install setuptools==67.6.1

问题完美解决了。
