Question

Am I able to use Paperclip in a straight ruby script run from commandline, without rails etc?

I need the Paperclip::Geometry functionality in a small ruby script I am trying to write, but it seems it needs a lot of dependencies that are a part of RoR. Is it possible to use Paperclip::Geometry without rails?

Answer 1

You can use it w/o Rails (f.ex in some commandline ruby scripts, in Sinatra, etc), but you must have some Rails parts installed on your system.
At least following ones, with their dependencies too:

#gem dependency paperclip
Gem paperclip-2.4.5
  activerecord (>= 2.3.0)
  activesupport (>= 2.3.2)
