# Install pyenv from homebrew:
brew install pyenv
pyenv install 3.7.4
pyenv global 3.7.4

# Install virtualenvwrapper globally:
$(pyenv which pip) install virtualenv virtualenvwrapper

# Update your ~/.bash_profile to include:

export VIRTUALENVWRAPPER_PYTHON=$(pyenv which python)
export VIRTUALENVWRAPPER_VIRTUALENV=$(pyenv which virtualenv)
source $(pyenv which virtualenvwrapper.sh)
    
export PIP_REQUIRE_VIRTUALENV=true

# And 
source ~/.bash_profile

# At this point, Python3 will be used in any new virtualenv; if you want to use Python3 directly, you can run pyenv which python3 and/or softlink this location into your $PATH.
