game not working after install

[berlintam]

After install, I can't start the game! I have ruby version 2.1.1p76. The install from rubygems seemed to work thou (no error messages)

Hey Tam, this appears to be the issue: gosu/gosu#199.

@RapidRailsGirls I think we can fix this by allowing the latest version of gosu (currently 0.8.5) instead of specifying 0.7.50. After making that change to carpet_diem.gemspec, you’ll need to release a new version of the gem.
