How to Run Your Unpublished Gem

There are 3 possible ways to run it.

• ruby -I lib bin/gem_command_name

• bundle exec bin/gem_command_name

  If you get a bundler: not executable: bin/gem_command_name error, run chmod +x bin/gem_command_name

• bundle exec gem_command_name

  We currently haven't figured out why the last command doesn't work.
