【问题描述】：

我在this 之后为 python 3 安装 dlib，因为 pip 不起作用，我从源文件 (setup.py) 安装它。 但是，发生了错误：

-- Building for: NMake Makefiles
CMake Error at CMakeLists.txt:5 (message):



  !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


  You must use Visual Studio to build a python extension on windows.  If you
  are getting this error it means you have not installed Visual C++.  Note
  that there are many flavors of Visual Studio, like Visual Studio for C#
  development.  You need to install Visual Studio for C++.

如何解决这个问题？另外，我使用的是 Python 3.9.4。而且，似乎我需要为 C++ 安装 Visual Studio。但是我在哪里可以找到呢？

【问题讨论】：

it seems like I need to install Visual Studio for C++. But where can I find that? → visualstudio.microsoft.com/vs/features/cplusplus

错误日志一目了然。您必须为“编译器、构建工具和运行时”安装 Visual Studio for C++，作为您提供的链接上@Rajat Bhatt 的答案。我相信你花在阅读所有答案上的时间肯定比写一个新问题 + 等待别人帮助的时间要短。

【参考方案1】：

许多二进制文件依赖于 Microsoft Visual C++ Redistributable for Visual Studio 2015、2017 和 2019 for Python 3

所以，请尝试使用以下代码来解决它

pip install --upgrade setuptools

如果你没有成功解决这个问题，

那么你可以尝试使用这个链接The latest supported Visual C++ downloads来安装这个问题
