python - 无法在 python 3.8 中导入 pyplot

问题描述

我已经matplotlib在 archlinux 中安装了 pacman

> $ pacman -Q python-matplotlib                                                                                              
python-matplotlib 3.3.0-1

但是当我输入python

> $ python                                                                                                                   
Python 3.8.3 (default, May 17 2020, 18:15:42) 
[GCC 10.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

然后运行import matplotlib.pyplot

>>> import matplotlib.pyplot as plt

我收到此错误消息：

有人遇到这个问题吗？

解决方案

您需要安装pillow库，因为它是matplotlib. 请参阅依赖项部分 - https://matplotlib.org/3.3.0/users/installing.html

pip install pillow
