How to run bootstrap.py to setup Firefox code base?

Question

I followed the steps provided here. I ran python bootstrap.py, it prompted me to enter a choice, I entered 2, Firefox for Desktop Artifact mode.

How to resolve this?

Answer 1

The guide you linked reports 2 important things:

1. Python must be version 2.7.11 (and you're using 2.7.13).
2. The script can error out if you already have Homebrew/MacPorts

The first problem can be solved, as reported by the guide, by using pyenv.

The second problem should be fixed by updating the Homebrew environment:

brew update && brew upgrade
