Answer 1

我是一名初学者，所以我不太了解究竟是什么导致了问题。当我安装 python 3.9 时，我遇到了同样的问题，但是当我将它降级到 Python 3.8 时，它对我来说很好

Answer 2

这个错误的解决方案就在那里。你需要在你的系统中安装 Microsoft Visual C++ 14.0，伙计。

https://visualstudio.microsoft.com/downloads/

使用此网站下载适用于您 PC 的 Visual Studio。

如果根本没有，那么请尝试使用以下方法：

1. 转到我在下面给出的网站

   https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

2. 下载所需版本的numpy

   例如，我在 Win64 中使用的是 Python 3.9，所以我选择

   numpy‑1.20.2+mkl‑cp39‑cp39‑win_amd64.whl

3. 然后，以管理员身份打开 CMD 并导航到您下载文件的文件夹

4. 然后输入

   pip install <name of file you downloaded>

就我而言，

pip install numpy‑1.20.2+mkl‑cp39‑cp39‑win_amd64.whl

安装成功！！！

请记住，首先在您的计算机上下载并安装 MS C++ 14.0，然后尝试！！！

Answer 3

我遇到过这个问题。我认为是因为 python 3.9。所以你可以卸载它并使用python 3.8，它会为你工作的。
