我在Windows 10上使用pypy3.6-v7.3.0。我正试图在安装numpy时使用 pip install numpy但我一直收到错误信息 error: Microsoft Visual C++ 14.1 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/.
然而我已经安装了Visual Studio Community 2019，而且我的C++构建工具完全是最新的。
编辑。
这是我手动安装构建工具后得到的新错误。

我不再看到原来的错误了，我现在无论如何都会得到这个错误。我试着用 pip install numpy, pip3 install numpy和 pypy -m pip install numpy. 所有的输出都是一样的。
(这是填充文字，因为它不允许我放这么多 "代码"，不做更多解释)

如果你的构建工具不能解决你的问题，请尝试通过以下方式手动安装构建工具。联系.
之后，你必须重新启动你的电脑或笔记本电脑。
然后尝试 pip3 install numpy. 在python 3.x版本中，我们使用 pip3 不 pip.
pip install numpy‑1.9.2+mkl‑cp34‑none‑win_amd64.whl
尝试直接从轮毂包安装。
