Creating virtual environment with venv

[arilev]

I'm pulling my hair out trying to install Flask on my Mac. I have Python 3.8.0. I'm trying to create a virtual environment using the python3 -m venv venv string and I get invalid syntax. Any suggestions?

how are you trying to do so?
It cannot be done from python interpreter, must be done from command line
