Make sure that `gem install rmagick -v '2.13.1'` succeeds before bundling.

On trying to install rmagick using this gem install rmagick -v '2.13.1'

I'm getting this error...

  • do you have devkit installed in your path? Commented Oct 7, 2012 at 8:19
  • Yes, devkit is installed. But don't know about its path? Pls explain. Commented Oct 7, 2012 at 8:56
  • do on your command prompt set PATH=%DEVKIT_HOME%\bin;%PATH% before running gem install rmagick from same terminal. This is assuming your DEVKIT_HOME variable resolves to your devkit installation directory Commented Oct 7, 2012 at 9:22
  • My path to devkit is c:\Ruby187\devkit, pls advise. Commented Oct 7, 2012 at 9:23
  • so just prepend it to your path I.e. set PATH=c:\ruby187\devkit\bin;%PATH% and then run gem install rmagick from same terminal Commented Oct 7, 2012 at 9:45

From comments, it appeared to work for others.. Note that I have switched to a different solution altogether so can't say that whether it works for me or not! But as it worked for others, I'm accepting this as an answer.

Did you install Imagemagick first? http://www.imagemagick.org

Actually, see : Won't Let Me Install Gem in Ruby Prompt

Yes, still it doesn't work. One thing I noticed is ROR sucks, there isn't proper documentation on anything, and even after spending countless hours in last two days, it throws one error after another and finally I've decided to use Bitnami installer rather then installing it as per instruction.

sudo apt-get install libmagickcore-dev libmagickwand-dev

and after run bundle install
