pyenv reminder

(i’m looking at you gsutil and gcloud) elmo(~)% pyenv global 3.7.1 2.7.15 elmo(~)% pyenv versions system * 2.7.15 (set by /Users/sulrich/.pyenv/version) 2.7.15/envs/foo 2.7.5 * 3.7.1 (set by /Users/sulrich/.pyenv/version) 3.7.2 foo elmo(~)% which python2 /Users/sulrich/.pyenv/shims/python2 elmo(~)% which python3 /Users/sulrich/.pyenv/shims/python3 elmo(~)% which python /Users/sulrich/.pyenv/shims/python elmo(~)% python --version Python 3....
