$ which brew

$ brew install pyenv

Install python 3.9.7

Configure shell to use this new python

$ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.profile
$ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.profile
$ echo 'eval "$(pyenv init --path)"' >> ~/.profile
$ echo 'if [ -n "$PS1" -a -n "$BASH_VERSION" ]; then source ~/.bashrc; fi' >> ~/.profile

$ echo 'eval "$(pyenv init -)"' >> ~/.bashrc

Now open up a new shell so that the entries in ~/.bashrc take effect. From that new terminal...

Have pipenv create a new virtualenv for the project

pipenv shell
