python - 为什么Matplotlib在VSCode上不起作用

我写了一个基本的绘图代码，然后以某种方式无法在VS代码上运行它

我删除了python本身和VS代码，然后再次下载了它们，但问题仍未解决。

import matplotlib.pyplot as plt
x = [1,2,3]
y = [4,5,6]
plt.plot(x,y)
plt.show()


Traceback (most recent call last):

    from matplotlib import rcParams
ImportError: cannot import name 'rcParams' from 'matplotlib' (C:\Users\xxx\AppData\Local\Programs\Python\Python37\lib\site-packages\matplotlib\__init__.py)

知道为什么会这样吗？

最佳答案

似乎您正在从包含名为copy的模块的目录中运行代码，该模块正在从stdlib中屏蔽copy模块（c:\Users\xxx\Desktop\Cmpt Physics\copy.py似乎是罪魁祸首）。将该文件重命名为与stdlib中的名称不同的名称，它应该可以解决该问题。

通常，对stdlib进行阴影处理会导致类似这样的奇怪结果：将stdlib乱序插入模块或错误的模块，并使事情以奇怪的方式破坏。
