MiniMagick - cannot load such file

Question

I'm trying to use MiniMagick to resize images and I did the following in my controller file:

require 'rubygems'
require 'mini_magick'

and

img = MiniMagick::Image.open(file)

But when I invoke the controller the following

LoadError (cannot load such file -- mini_magick)

I've added gem 'mini_magick' to my Gemfile so I have really no idea what's going on. Can someone help me with this?

BTW, it is available in both irb and rails console, but not when run as a server.

Thx in advance.

Are you running the server from the command line (i.e., rails server) or through an IDE? — Dave Isaacs, Apr 19 '13 at 15:36
Hmmm, if you were running through an IDE I was going to suggest making sure your IDE is running in an environment equivalent to the command line. I don't know anything about Unicorn, however :( — Dave Isaacs, Apr 19 '13 at 15:49

:D "Have you tried turning it off and on again?" should be a prerequisite checkbox when submitted a StackOverflow question. – Dave Isaacs Apr 19 '13 at 16:34

I was also facing this issue. Just uncomment the line

include CarrierWave::MiniMagick

in your uploader file and make sure you have commented the line

include CarrierWave::RMagick

So your setting in uploader file should look like this:

# include CarrierWave::RMagick
include CarrierWave::MiniMagick

Some times this problem is caused by not having the latest version of the gems. It can be fixed by running bundle update.

Whenever you have this error just add gem "mini_magick" and restart your server using the rails s command. But most importantly, remember to always check your server logs on your terminal for the error message. They are your best friend in figuring out the solution you need for your problem.
