I'd like to install QGIS. I'm on a system that defaults to Python 2.5x and I downloaded python 3.7x with homebrew. I created a virtual environment with this code.
brew install pyenv brew install pyenv-virtualenv exec $SHELL eval "$(pyenv init -)" eval "$(pyenv virtualenv-init -)" pyenv activate my-virtualenv
I install python 3.6 and the modules
Each of them are confined to the virtual environment. How do I install the package so that it loads and uses the Python from only the partcular environment.
