Hmmm, a good question. I don't know the definitive answer since I
also understand that rmagick needs imagemagick.
When I call gem dependency for myself, some gems just return
themselves and nothing else.
anita@anitas-computer:~$ gem dependency heroku
Whereas gems that I know require other gems return the other gems.
anita@anitas-computer:~$ gem dependency rails
rake (>= 0.8.1)
activesupport (= 2.1.0)
activerecord (= 2.1.0)
actionpack (= 2.1.0)
actionmailer (= 2.1.0)
activeresource (= 2.1.0)
But in my own experiments, I don't see any reference to any libs
identified that fall out of the rubygems arena. Not sure how to
access the dependencies on non-gem libs either.
But the fact that irb returned true when given the require "rmagick"
command gives me confidence that rmagick is successfully required when
needed. Meaning that the gem path allows the gem to be fetched when
So if the paths are working and the gem responds when invoked, I don't
know what could be standing in the way of your app responding. Is
this in development on your home environment or is this app on a
server (development or production?). Has the app been frozen? Is
there anything in any of the directories such as vendor where the app
is going to fetch the gems rather than going to the directory outlined
when you ran => gem env ?
Those are all the other influences that I can think of at the moment.
And time for me to sign off for the night.
Best of luck, let me know what you discover.
