尝试导入 matplotlib 时没有名为“kiwisolver”的模块

Question

我正在尝试在 Python 中绘制一些数据，因此需要 matplotlib。 尝试导入时，我得到了ModuleNotFoundError。

引发错误的行是

import matplotlib.pyplot as plt

我安装的包包括（根据 PyCharm 的 Python Interpreter Menu）：

matplotlib==3.3.4
numpy==1.20.1
pandas==1.4.3
kiwisolver==1.3.1

在找到这个之后：github.com/nucleic/kiwi/issues/68 我卸载并重新安装了 kiwisolver，由于某种原因它现在可以工作了
