On the Mac, we recommend installing brew, https://brew.sh/. Then installation
is as simple as `brew install pyenv pyenv-virtualenv` and adding this to your
profile:
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

cat << 'END_OF_LINE'
For Linux, Windows Subsystem for Linux (WSL), or on the Mac (if you don't want
to use "brew") you can use https://github.com/pyenv/pyenv-installer to install
the necessary tools. Before running this ensure that you have installed the
prerequisites for your platform according to the pyenv wiki page,
https://github.com/pyenv/pyenv/wiki/common-build-problems.
On WSL you should treat your platform as whatever Linux distribution you've
chosen to install.
Once you have installed "pyenv" you will need to add the following lines to
your ".bashrc":
export PATH="$PATH:$HOME/.pyenv/bin"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
