pip3 install matplotlib==2.2.2
出现新的问题,ImportError: Matplotlib qt-based backends require an external PyQt4..., PyQt5,PySide or PySide2 package to be installed, but it was not found....解决方法:安装PyQt5
pip3 install PyQt5
安装后仍出现2中的问题,应该是缺少PySide
解决方法,安装PySide
pip3 install PySide
安装PySide时报错...1 lines):only these python versions are supported: [(2, 6), (2, 7), (3, 2), (3, 3), (3, 4)]
解决方法:安装PySide2...pip3 install PySide2
