ruby on rails 3 - carrierwave + mini_magick gems = not an image error

Question

I'm using:

- carrierwave 0.6.0
- rails 3.2.1
- mini_magick 3.4
- ruby 1.9.2p290

And during image uploading I want to resize uploading pic:

(image_uploader.rb)
process :resize_to_fit => [200, 200]

But after image uploading I've got an error:

1 error prohibited this organization from being saved:
Image image Failed to manipulate with MiniMagick, maybe it is not an image? Original Error: MiniMagick::Invalid

PS. If I'm not resizing, image upload works fine.

PS2. I tried to add in config/environment.rb:

require 'rubygems'
require "mini_magick"

but without success (still not working - btw. is it required when using mini_magick as a gem?)

Answer 1

I'm sure that you've solved this by now (at least hopefully! It's almost two months later!), but here's a solution that worked for me just now:

---

Uninstall imagemagick through homebrew:

• brew uninstall imagemagick

Clean your homebrew directory:

• brew cleanup --force -s
• --force removes all out of date keg-only brews, -s removes all cached downloads

Reinstall imagemagick:

• brew install imagemagick

---

After all of that, you should be good to go!
