Error while installing dlib?

Question

pip

It all started with the fact that I decided to put face_recognition (on Windows). When installing via pip, I got a huge error. As I found out later, it appeared exactly when installing dlib. I have read many forums. Now I already have Anaconda, cmake, cmake added to environment variables. All the same dlib is not downloaded. Tried through whl file again error. I don't know what to do anymore. Here is the error

Running setup.py install for dlib ... error

  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++.

And it seems that here it is, it’s written here in plain text, you don’t have Visual c ++, but the fact is that I tried to download it about 10 times already, different versions, and so on. None of them affect the installation in ANY WAY. The error remains the same. What to do??
