sudo pip install matplotlib
安装 matplotlib 时出现以下错误
Found existing installation: pyparsing 1.5.6
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.
安装 matplotlib 需要卸载我已安装的 1.5.6 版本的 pyparsing,再重新装新版本,但是无法卸载
手动重装最新版 pyparsing
首先,去官网查看最新版是什么版本:https://pypi.org/project/pyparsing/
当前最新版是 pyparsing 2.2.0
,所以执行如下重新安装最新版:
sudo pip install -I pyparsing==2.2.0
