我尝试使用 pip 下载 dlib，但结果如下：

  ERROR: Failed building wheel for dlib

这很奇怪，因为我确实安装了 CMake，甚至重新启动了我的电脑。我还将站点包的路径添加到我的 PATH 环境中。我还确保 pip 已升级到最新版本，并尝试从 github 手动下载 zip 版本并通过解压缩文件并以管理员身份运行 setup.py 来安装它。我遇到了完全相同的错误代码。

有人可以帮忙吗？提前非常感谢您！

【参考方案1】：

1.使用python 3.6.9版本

2.首先安装cmake。

conda install -c anaconda cmake

使用这些命令安装 dlib

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