When you have the C++ compiler installed on your PC(let's assume that you are on Windows), it creates a Python development environment by default. And trying to install any package you might get this message: Failed building wheel for ninja

Note: First you have to remove your virtual environment

To solve this problem press

1. Press Ctrl+Shift+P
2. Python: Select Python Interpreter
3. Create Virtual environment
4. And select the python version you installed globally

Don't select the one which says msys64
