VSCode v1.35 - RuntimeError: CMake must be installed to build the following extensions: dlib

Question

I have already installed CMake by pip install cmake and tried to install face_recognition but it still gives me a RuntimeError. I'm using 'Python 3.7.3, x32'

I also tried to install the dlib by pip install dlib since it is one of the reasons why I can't install face_recognition.

C:\Users\user>python -m pip install cmake
Requirement already satisfied: cmake in c:\users\user\appdata\roaming\python\python37\site-packages (3.14.4)

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

Answer 2

What works for is ... After getting lots of Red Errors, I run following

1. conda install -c conda-forge dlib
2. pip install cmake
3. pip install face_recognition

Even the error says me to reinstall VS Code for c++. but above sequential installation works.

Python version was 3.8
