无法安装 numpy - 需要 MS Visual C++ 14.1。但是安装好了
Can't install numpy - MS Visual C++ 14.1 is required. But it is installed
我正在 Windows 10 使用 pypy3.6-v7.3.0。我正在尝试使用 pip install numpy 安装 numpy，但我不断收到错误消息：error: Microsoft Visual C++ 14.1 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/.
但是我已经安装了 Visual Studio Community 2019，并且我的 C++ 构建工具完全是最新的。
编辑：
这是我在手动安装构建工具后遇到的新错误：

我再也看不到原来的错误了，无论现在如何，我总是会收到这个错误。我尝试使用 pip install numpy、pip3 install numpy 和 pypy -m pip install numpy。都给出相同的输出。
pip install numpy‑1.9.2+mkl‑cp34‑none‑win_amd64.whl
尝试直接从 wheel 包安装。
如果您的构建工具无法解决您的问题，请尝试通过此 link 手动安装构建工具。
之后您必须重新启动您的 PC 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 而不是 pip.
某些版本的 Visual C++ 构建工具之间有明显的区别。
- Visual studio 版本 2015 构建工具 -> VC 14.0
- Visual studio 2017 版构建工具 -> VC 14.1
- Visual studio 2019 版构建工具 -> VC 14.2
相应地从菜单中选择您需要的构建工具：
https://visualstudio.microsoft.com/vs/older-downloads/
我正在 Windows 10 使用 pypy3.6-v7.3.0。我正在尝试使用 pip install numpy 安装 numpy，但我不断收到错误消息：error: Microsoft Visual C++ 14.1 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/.

我再也看不到原来的错误了，无论现在如何，我总是会收到这个错误。我尝试使用 pip install numpy、pip3 install numpy 和 pypy -m pip install numpy。都给出相同的输出。
pip install numpy‑1.9.2+mkl‑cp34‑none‑win_amd64.whl
尝试直接从 wheel 包安装。
如果您的构建工具无法解决您的问题，请尝试通过此 link 手动安装构建工具。
之后您必须重新启动您的 PC 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而不是pip.
某些版本的 Visual C++ 构建工具之间有明显的区别。
- Visual studio 版本 2015 构建工具 -> VC 14.0
- Visual studio 2017 版构建工具 -> VC 14.1
- Visual studio 2019 版构建工具 -> VC 14.2
