python - Error in installing face_recognition module using pip

Question

I am using vs code in windows 10. When I install face_recognition in vs code using pip I got the following error, I have also tried to install dlib before installing face_recognition.

      You must use Visual Studio to build a python extension on windows.  If you
      are getting this error it means you have not installed Visual C++.  Note
      that there are many flavors of Visual Studio, like Visual Studio for C#
      development.  You need to install Visual Studio for C++.

Answer 1

The answer is really simple. You have to do what it says. Go to the VS installer and install VS for C++ and C#. The reason is that these modules use C code and while using Visual Studio, you have to make it so that it can compile the C++ code
