Is there a best practice for when an app requires a gem?

Hi there,

Is there a standard/recommended way for a Rails app to express a
dependency on a gem? For non-rails projects, we could package as a gem
and hence use the gem spec to express dependencies.

I suppose I could do it by hand in environment.rb, but it seems like
there ought to be a cleaner way. Am I missing something?

Thanks,

Brian H.

Try this: The program emits “no such file to load – foo”

The user responds with: sudo gem install foo

Problem solved. Just don’t go crazy and call your primary include file
‘luxury_yacht’, while your gem is called ‘throat_warbler_mangrove’. Name
them
the same so the error message

The rule “same thing same name” is a very important tenant of lean and
clean
programming.
