How to solve error when installing auto-py-to-exe?

Question

I am trying to pip install auto-py-to-exe, but got following error.

error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for 
Visual Studio": https://visualstudio.microsoft.com/downloads/

I also tried to download wheel or .gz file and install but it gave me the same error.

Here the full error message goes.

Thank you in advance.

Try to install Microsoft Visual C++ 14.0.

error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio":
https://visualstudio.microsoft.com/downloads/

You should go on Visual C++ 2015 Build Tools to install Visual C++ 14.0 without installing Visual Studio.
