【问题描述】：
我正在尝试使用 pandas python 进行 excel 操作。
每当我尝试使用 pandas 库时，都会出现错误提示未安装 numpy。
现在，当我尝试执行 pip install numpy 和 pip install pandas 时，它显示要求已经满足.
但是当我尝试做一个简单的 numpy 教程时，它在 numpy 的导入语句上出错。

看起来你的 NumPy 安装在某种程度上被破坏了。也许使用
pip install --force-reinstall numpy强制重新安装软件包，然后重试。 -
我已经尝试过，但我仍然收到错误消息。当我执行重新安装时，我注意到在安装时它说它正在使用缓存的 numpy 库。我将尝试获取 numpy 轮并手动安装。参考：来自stackoverflow.com/questions/29499815/…的第二个答案
