rvm requirements - fails with status: 141 when installing gcc49 on macOS

[newswim]

Description

RVM does seem to be working, however the gcc49 installation step seems to be failing when I run rvm requirements.

Environment info

• RVM version: rvm 1.27.0 (master)
• Operating System: macOS
• Version/Release: 10.12
• Shell: zsh
  

  Expected behavior

rvm requirements should install Ruby dependencies according to this cheatsheet

Actual behavior

command hangs, even after waiting many minutes. This is the dialogue:

Installing required packages: gcc49../

Output

Requirements installation failed with status: 141.

Steps to reproduce

1. Install RVM
2. run rvm requirements

Note, rvm does install and this does not appear to be affecting anything yet.

It seems like a gem requiring gcc may cause an error in the future, though.

Also I realize Sierra is not supported yet, so if I've made an error in reporting this, please let me know.

[pkuczynski]

RVM is using Homebrew to install required libraries. Have you tried to run brew doctor? You might want to isolate the problem and install gcc49 using brew itself: brew install gcc49.

Make sure you have latest brew installed (brew update)

[newswim]

This is indeed where the problem is arising - attempting to run brew install gcc49, it's still running and I'll provide current output for contrast.

Apparently this can take up to 45 minutes

-- update, it did finished. I didn't realize gcc would take so long to compile.

ln -s ../Cellar/gcc49/4.9.3/lib/gcc gcc
