【问题描述】：

我是 Python 新手，我想复制本教程：https://www.youtube.com/watch?v=wQ8BIBpya2k 但是当我尝试导入 Matpotlib.pylot 时出现此错误：“ModuleNotFoundError: No module named 'matplotlib.pylot'”所以现在我尝试安装Pylot 手动，但它给我一个语法错误：

D:\Python>pip3 install --upgrade --no-cache-dir pylot

【参考方案1】：

matplotlib 中的模块 被称为pyplot，而不是pylot。 PyPI 上的 pylot package 与 matplotlib 完全无关。
