Ruby on Rails RMagick gem install issue

Question

(Edit: see bottom for solution) I am making a Ruby On Rails project and am trying to install the RMagick gem. Using OS X 10.6, Ruby version 2.0.0p247, Rails 4.0.0, RVM 1.22.12.

When I run a bundle install I get the following error:

...
Installing rmagick (2.13.2) 
Errno::EACCES: Permission denied - /Users/jasonpather/.rvm/gems/ruby-2.0.0-p247/g
ems/rmagick-2.13.2/build_tarball.rake
An error occurred while installing rmagick (2.13.2), and Bundler cannot continue.
Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling.

So then I try the suggestion:

Jason-Pathers-MacBook-Pro:BuyABrick jasonpather$ gem install rmagick -v '2.13.2'
ERROR:  While executing gem ... (Errno::EACCES)
Permission denied - /Users/jasonpather/.rvm/gems/ruby-2.0.0-p247/gems/rmagick
-2.13.2/build_tarball.rake

So then I try sudo:

Jason-Pathers-MacBook-Pro:BuyABrick jasonpather$ sudo gem install rmagick -v '2.1
3.2'

I would very much appreciate any help. I've looked at similar questions on this site but none of the suggestions have helped. Do I need to install other packages before I install RMagick or something?

Edit: solution

I simply used homebrew to install imagemagick brew install imagemagick then sudo gem install rmagick and now bundle install runs fine!

Answer 1

You need to install Image Magick (checking for Magick-config... no from your log suggests that).

The easiest way to do that (since you are on mac) is with Homebrew. Install Homebrew (follow any instructions it gives you during install — they aren't many) and then just run:

brew install imagemagick

Then run bundle install again.
