我已经在系统上安装了pytest。当我使用pytest运行命令时。我遇到以下错误。
Traceback (most recent call last):

raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'pathlib2>=2.2.0' distribution was not found and is required by pytest
此外，我在CLI上输入了“ pip install pathlib2”
Requirement already satisfied: pathlib2 in /usr/local/lib/python2.7/site-packages (2.2.0)
Requirement already satisfied: scandir in /usr/local/lib/python2.7/site-packages (from pathlib2) (1.9.0)
Requirement already satisfied: six in /usr/local/lib/python2.7/site-packages (from pathlib2) (1.11.0)
但是它不起作用，同样的错误。
