这是在命令提示符下使用pip安装dlib时出现的错误。 我已经有了openCV，matplotlib和numpy。

Answer 1

我以前也遇到过同样的问题。我做了几件事，而且成功了

< P>安装C和C++编译器并将它们添加到路径中。

1. 安装visual studio 2015（VS2015）下载程序。（任何其他版本都可能不起作用）。此堆栈溢出线程可能有帮助：How to download Visual Studio Community Edition 2015 (not 2017)

> P>通过VS2015安装所有依赖关系（支持C、C++、MS Bug、Windows SDK等）
3. 再次尝试使用pip install dlib。

我希望这有帮助！

Answer 2

我在安装dlib时遇到了许多错误，请使用以下命令解决。whl：

 pip install https://pypi.python.org/packages/da/06/bd3e241c4eb0a662914b3b4875fc52dd176a9db0d4a2c915ac2ad8800e9e/dlib-19.7.0-cp36-cp36m-win_amd64.whl#md5=b7330a5b2d46420343fbed5df69e6a3f

从这个link下载控制盘

这可能有帮助：）

Answer 3

您可能需要首先安装cmake：“pip install cmake”

然后安装dlib，即：“pip install dlib”。

一定能百分之百发挥作用。

注意：你必须有一个快速处理器来制造轮子，否则需要5分钟以上。
