virtualenv install on Python 3.7 Mac 10.15.7 successful but not working

Question

I need to create a Python 2.7 virtual environment to run code that only works in Python 2.7

I installed virtualenv successfully with pip

q@Q-336-MacBook-Pro:~/Documents/science_rcn> pipx install virtualenv
'virtualenv' already seems to be installed. Not modifying existing installation in '/Users/qliu/.local/pipx/venvs/virtualenv'. Pass '--force' to force installation.

q@Q-336-MacBook-Pro:~/Documents/science_rcn> virtualenv --help
-bash: /usr/local/bin/virtualenv: /usr/local/opt/python/bin/python3.7: bad interpreter: No such file or directory

But when I try to use it I get -bash: /usr/local/bin/virtualenv: /usr/local/opt/python/bin/python3.7: bad interpreter: No such file or directory

What's going on?
