Answer 1

I don't know about installation by PyCharm. Try to install package by pip install numpy from cmd.

Answer 2

PyCharm tries to install the numpy sources and compile them (although I don't know why) you need a working compiler for this. You could try to install the numpy (binary) packages with a default pip into your venv.

1. Open "cmd"
2. Go to correct dir: cd "C:\\Users\\Badboy\\PycharmProjects\\my python projects"
3. Activate the venv with the command: venv\\Scripts\\activate.bat
4. A new prefix (venv) should appear in your cmd
5. Install NumPy: pip install numpy
