解决 Cannot uninstall 'pyparsing' 问题

在安装 pydot 时遇到依赖 pyparsing 没法更新问题：

Successfully built pyparsing
Installing collected packages: pyparsing
  Found existing installation: pyparsing 2.0.1
Cannot uninstall 'pyparsing'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

解决方法是手动重装最新版 pyparsing：

sudo pip install -I pyparsing==2.2.0

2019.1
