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 和 matplotlib 和 numpy。

【问题讨论】：

您发布的错误消息部分是通用的，并且会显示在任何错误上。请显示完整的错误。

@hoefling 已更新，请检查您是否可以帮助我

【参考方案1】：

不久前我遇到了同样的问题。我做了一些事情，它奏效了

安装 C 和 C++ 编译器并将它们添加到路径中。

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：How to download Visual Studio Community Edition 2015 (not 2017)

通过VS2015安装所有依赖。（支持C、C++、MS Build、windows SDK等）

再次尝试使用 pip install dlib。

我希望这会有所帮助！

【讨论】：

如果我用 c 和 cpp 包安装 Visual Studio 那么它可以工作吗？

您也需要安装这些，但您还需要 c 和 c++ 编译器，如 gcc.exe 和 g++.exe。您必须将这些添加到环境路径变量中。

我已经安装了 minGW，现在我有 gcc 和编译平台可以工作了

能不能分享下要下载的编译器的链接。

mingw32-gcc-dev, mingw32-gcc-bin, mingw32-gcc-g++dev, mingw32-gcc-g++bin

【参考方案2】：

对于那些面临同样问题但使用 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

【讨论】：

根据问题中的错误，作者运行的是Windows而不是macOS。

哦，我只是为任何使用 macOS 并面临同样问题的人发表评论。很抱歉没有澄清！

在 linux 机器上也为我工作过。 （在 Ubuntu 主机上运行 CoCalc 的 Docker 映像，以防您对细节感兴趣。）

【参考方案3】：

在这里记录一下：在 debian 10 上。pip install dlib 失败，即使首先使用 pip install cmake。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，可以让你的代码运行得更快。事实证明，如果不先安装它，每次安装都会失败。安装成功。

【参考方案4】：

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% 工作。

注意：你必须有一个快速的处理器来构建***，否则它需要超过 5 分钟。

【参考方案5】：

我在安装 dlib 时遇到了很多错误，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

从此link下载轮盘

这可能会有所帮助:)

【讨论】：

dlib-19.7.0-cp36-cp36m-win_amd64.whl 不是该平台支持的***。

这是我运行上述行进行安装时得到的结果

您尝试在哪个平台上执行窗口？

是的，我正在使用 Windows，并使用命令提示符和 pip install 命令进行安装

试试这个 pip install files.pythonhosted.org/packages/24/ea/…
