I've just set up m-c on another laptop and I've run into an interesting problem:

Error: python 2.7.12_2 is already installed
To upgrade to 3.7.0, run `brew upgrade python`
Traceback (most recent call last):
  File "bootstrap.py", line 176, in <module>
    sys.exit(main(sys.argv))

subprocess.CalledProcessError: Command '[u'/usr/local/bin/brew', u'install', u'python3']' returned non-zero exit status 1

I don't think this should quit bootstrap.py and just continue. However, the ./mach build command checks for Python 3 and then complains. I *guess* I could run the brew upgrade to 3.7 and then everything would be fine, but I wonder if there is a better way to communicate that. given that volunteers run that script and might not have experience with bootstrapping m-c, this is a quite intimidating error message IMHO. Also, shouldn't this be in a virtualenv? Not everyone wants to have 3.7 installed outside of a virtualenv..

This also leads to

hg: unknown command 'push-to-try'
