Running pytest on mac - command not found: pytest

Installing pytest with pip will return the following error.

learnGPT-team2 % pytest test_ex.py -s -vv
zsh: command not found: pytest

In this case, try python -m pytest

Installing pytest via pip doesn’t make it a system command, it installs it to python. The -m command runs pytest as its own command and then any proceeding script will be an argument.

python3 -m pytest test_ex.py -s -vv
