这是我在命令提示符下使用 pip 安装 dlib 时遇到的错误。我已经有了 openCV、matplotlib 和 numpy。

Answer 1

我在安装 dlib 时遇到很多错误，并使用下面的 .whl 解决：

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

从这里下载 wheel link

这可能有帮助:)

Answer 2

前段时间我遇到了同样的问题。我做了一些事情并且奏效了

安装 C 和 C++ 编译器并将它们添加到路径。
安装 visual studio 2015 (VS2015) 下载器。（任何其他版本可能不起作用）。这个堆栈溢出线程可能会有所帮助：
通过 VS2015 安装所有依赖项。（支持 C、C++、MS Build、windows SDK 等）
再次尝试使用 pip install dlib。

希望对您有所帮助！

Answer 3

您可能需要先安装 cmake：“pip install cmake”

然后安装 dlib 即：“pip install dlib”。

肯定会 100% 有效。

注意：你必须有一个快速的处理器来构建轮子，否则它会超过 5 分钟。

Answer 4

对于那些遇到同样问题但使用 mac OS 的人 --> 我执行了以下步骤并解决了同样的问题。我有 macOS Big Sur 11.1 和 python 3.8.3.

pip3 install cmake 
pip3 install dlib

Answer 5

这里记录一下：在 debian 10 上。pip install dlib 即使先 pip install cmake 也会失败。解决方案？ sudo apt install libopenblas-dev。 pip install dlib --verbose 的输出提到它是一个可选安装，可以使您的代码运行更快。事实证明，如果不先安装它，每次安装都会失败。有了它安装成功。
