ERROR : Could not build wheels for numpy which is required to install pyproject.toml-based projects

Why did this error(Could not build wheels for numpy which is required to install pyproject.toml-based projects) occur?

I guess.

---------------------------------------------------------------------------------------------1. From the control panel, it went to the Remove Program tab and removed the file sun.

2. Google searched python download 3.8 and downloaded Windows x86-64 extractable installer.

 

3. Installation of python-3.8.0-amd64.exe was performed.
   - PATH, that is, a variable path is selected.

--------------------------------------------------------------------------------------------

It's been solved.
