Failed building wheel for dlib Running setup.py clean for dlib Failed to build dlib

回答1:

I ran into this issue as well. I am using windows and have a python environment that I am installing the requirements to.

I ran pip install cmake , and then pip install dlib. I no longer received the error and successfully installed dlib.

I also had the same issue. For those who deals with it now -

Firstly you have to install visual studio, and than install there the extension "tools for CMake". Look at the installation part here: https://docs.microsoft.com/en-us/cpp/build/cmake-projects-in-visual-studio?view=vs-2019

Only after that you will be able to pip install this package.

So:

1. Install VS
2. Install the extension "tools for CMake"
3. Of course you should also have the python interpreter installed
4. In the command line:
   • pip install CMake
   • pip install face_recognition

Edit: Not checked, but if you don't have Visual Studio installed, try install "CMake Tools" separately, maybe from here: https://marketplace.visualstudio.com/items?itemName=vector-of-bool.cmake-tools
