需要 MS Visual C++ 14.1。但已经安装好了

问题描述 投票：0回答：4

我在 Windows 10 上使用 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：

错误：需要 Microsoft Visual C++ 14.1。使用“Visual Studio 构建工具”获取它：https://visualstudio.microsoft.com/downloads/`

但是，我已经安装了 Visual Studio Community 2019，并且我的 C++ 构建工具已完全更新。

这是我手动安装构建工具后遇到的新错误：

我不再看到原来的错误，无论现在如何，我总是会遇到这个错误。我尝试使用 

pip install numpy
、
pip3 install numpy
和 
pypy -m pip install numpy
。全部给出相同的输出。

python pip pypy

  1. 如果您的构建工具无法解决您的问题，请尝试通过此链接手动安装构建工具。

  2. 之后您必须重新启动您的电脑或笔记本电脑。

  3. 那就试试

    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++ 构建工具之间存在明显的区别。

  • Visual Studio 2015版构建工具-> 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

从菜单中相应地选择您需要的构建工具： https://visualstudio.microsoft.com/vs/older-downloads/

你也可以直接使用chocolatey的numpy包：

choco install numpy

pip install numpy‑1.9.2+mkl‑cp34‑none‑win_amd64.whl

尝试直接从wheel包安装。
