【中文标题】VSCode v1.35 - RuntimeError: CMake must be installed to build the following extensions: dlib【英文标题】： 【发布时间】：2019-11-05 22:53:30 【问题描述】：

我已经在我的 VS Code 1.35 中安装了 pip install cmake 的 CMake，并尝试安装 face_recognition，但它仍然给我一个 RuntimeError。我正在使用'Python 3.7.3，x32'

我还尝试通过pip install dlib 安装dlib，因为这是我无法安装face_recognition 的原因之一。

C:\Users\user>python -m pip install cmake

我希望有人可以帮助我解决这个问题。我是新手，真的是使用 python 的初学者，并尝试了其他问题的不同建议。希望有人会注意到我的问题。谢谢！

【参考方案1】：

从here下载并安装dlib轮

然后pip install face_recognition

pip install cmake 在visual studio，单个组件选项卡，编译器下用于 Cmake 的 Visual C++ 工具复选框，构建工具和运行时部分在 Visual Studio 命令提示符下运行，pip install face_recognition

Source

【讨论】：

我必须安装 Visual Studio 2019 或任何其他版本吗？即使我只是单独使用 Visual Studio 代码？或者试试dlib轮无需安装VSCode。我使用创建 python 虚拟环境版本 3.6 并安装了带有轮文件的dlib，因为它支持最高版本 3.6。然后pip install cmake & 然后pip install face_recognition。【参考方案2】：

有用的是... 在得到很多红色错误后，我运行以下

conda install -c conda-forge dlib

pip install cmake

pip install face_recognition

即使错误提示我重新安装VS Code for c++。但以上顺序安装工作。
