I have trouble installing rmagick. I am developing my project using ruby on rails framework. I included rmagick gem in my gemfile. I am getting the following error message:

checking for ImageMagick version >= 6.4.9... no
Can't install RMagick 2.13.4. You must have ImageMagick 6.4.9 or later.

I have installed imagemagick using brew:

 imagemagick-6.8.9-8 already installed

The imagemagick folder is resided in /usr/local/Cellar directory

In my terminal:

Zoulfias-iMac:Myapp zoulfiahall$ rvm use ruby-2.0.0-p481

Using /Users/zoulfiahall/.rvm/gems/ruby-2.0.0-p481
Zoulfias-iMac:Myapp zoulfiahall$ sudo gem install rmagick

Gem files will remain installed in /Users/zoulfiahall/.rvm/rubies/
ruby-2.0.0-  p481/lib/ruby/gems/2.0.0/gems/rmagick-2.13.4 for inspection.

Any advice will be appreciated.

This worked for me on ubuntu.

$ sudo apt-get install imagemagick
$ sudo apt-get install libmagickwand-dev

Now try again.

$ bundle install

    Thank you for posting this. It works but I also need to install the ruby-rmagick with the command `#apt install ruby-rmagick` – mohit May 09 '17 at 12:27
  • if possible pls try to relate why we need to install these libraries for proper working of ImageMagick. Similarly in other cases as well. – Sunil Kumar Oct 28 '18 at 11:14
  • @RememberWhyYouStarted I have no idea why its needed. It seems like the library has a dependency on the development libraries rather than just the production binaries. I have no idea why, only that it works. – justin.m.chase Oct 29 '18 at 15:21

I had this same issue on macOS when attempting to run gem install rmagick -v 2.13.4

The trick to this is the rmagick installer (gems/rmagick-2.13.4/ext/RMagick/extconf.rb) checks the output of convert to determine the IM version. If that is not returning the correct version (or otherwise completely broken, as was my case), rmagick will not install.

I installed ImageMagick 6 via Homebrew and that fixed my issue. This snippet installs IM, adds it to your path, and runs the installer explicitly pointing to IM6.

$ brew install imagemagick@6
$ echo 'export PATH="/usr/local/opt/imagemagick@6/bin:$PATH"' >> ~/.bash_profile
$ source ~/.bash_profile
$ PKG_CONFIG_PATH=/usr/local/opt/imagemagick@6/lib/pkgconfig gem install rmagick -v 2.13.4

Good luck!

I had the same problem today. What is causing the problem is the fact that rmagick is out of date. And the gem is not being updated regularly. I wanted to present my solution for people who don't mind using older version of imagemagick. ( I believe it is up to 6.5.9-10)

  1. Uninstall imagemagick with all the components:

    brew uninstall --force imagemagick

  2. Install the older version of imagemagick by adding -ruby186 to the end of the command

    brew install imagemagick-ruby186

  3. Install rmagick :)

    gem install rmagick

  4. Enjoy!

If do you installed imagemagick with brew install imagemagick@6

Before bundle install, run: 

export LDFLAGS="-L/usr/local/opt/imagemagick@6/lib"
export CPPFLAGS="-I/usr/local/opt/imagemagick@6/include"
export PKG_CONFIG_PATH="/usr/local/opt/imagemagick@6/lib/pkgconfig"

Just had same issue. Try uninstall imagemagick and then install again:

brew uninstall --force imagemagick
brew install imagemagick

Then install rmagick. This worked for me.

    This is the most minimalistic and straight-forward solution here and it worked well for me. I recommend others to try this one before trying the other ones. – adrianmcli Nov 06 '16 at 22:02

I filed a bug report for a similar issue at https://github.com/rmagick/rmagick/issues/126

I'm running crunchbang linux using debian sid.

It looks like you are on OSX. Consider filing your own bug report, if you havn't already.

This solved the issue for me in MacOS 10.14 Mojave

brew install pkg-config
PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick@6/6.9.11-0/lib/pkgconfig gem install rmagick -v 2.16.0
