Foreman and Thor incompatibility
There's currently an issue with foreman/thor that is effecting the GDK.
If you see an error like this, it's probably due to this issue:
/Users/connor/.rvm/gems/ruby-2.3.3/gems/thor-0.19.3/lib/thor/base.rb:534:in `thor_reserved_word?': "run" is a Thor reserved word and cannot be defined as command (RuntimeError)
