plt失败时导入matplotlib.pyplot

Question

首先，我可以很好地运行inlezen3.py脚本，并且可以使用matplotlib库进行绘图。突然，它再也找不到matplotlib模块，我在下面的代码行中得到一个错误：

import matplotlib.pyplot as plt

错误是找不到matplotlib模块：

ImportError: DLL load failed: Kan opgegeven module niet vinden.

整个错误回溯：

(code) PS C:\Users\Me\dev\2020-08-21_Analyse_Sunridge\code> python inlezen3.py
Traceback (most recent call last):
  File "inlezen3.py", line 14, in <module>

我尝试使用虚拟环境，并在此虚拟环境中再次安装所有必需的软件包。安装没有问题，但我再次得到同样的找不到模块错误

请帮忙

Answer 1

您可以在CMD type pip install matplotlib中重新安装它

Answer 2

我通过卸载python（在Windows应用程序管理器中）和下一次安装Anaconda解决了这个问题
