Python 3.7.3 (<- This is my version in summer of 2019) I am but a mere Python mortal so if anything I typed below is bad, go to the source posts for the real truth.Ġ/ You may need to install Xcode command line tools to start %terminal xcode-select -installġ/ Install Homebrew terminal% ruby -e "$(curl -fsSL )"Ģ/ Add it to your path by tacking this to the bottom of your ~/.login export PATH="/usr/local/opt/python/libexec/bin:$PATH"ģ/ To ingest that new command, type ‘source ~/.login’ terminal% 'source ~/.login'Ĥ/ Now install Python 3 as both python3 and python (it will become your default) terminal% brew install pythonĥ/ Test out that your Python 3 has been installed by asking what its version is terminal% python3 -version The basis for all these instructions are from the Python master at Guide to Python three posts: 1 2 3. If you want to run both versions, and you want to remember how to run in protected, virtual environments but you keep forgetting how to do it - this is the guide for you. Even though you might be, like me, tethered to Python 2.7 for some odd reason.
