An error occured while installing rmagick (2.13.1), and Bundler cannot continue.
Make sure that `gem install rmagick -v '2.13.1'` succeeds before bundling.

Note that I'm attempting to complete a redmine installation and need rmagick to continue using rake.

My ruby version is 1.8.7 and rubygem version is 1.3.7. Thanks.

Update:

So after hearing that my existing rmagick was an old version I ran:

gem uninstall rmagick

and successfully uninstalled my existing gem. After which I attempted a bundle install again which failed exactly the same as before.

This time however I went to my folder (C:\wamp\ruby\lib\ruby\gems\1.8\gems\rmagick-2.13.1) where it said the files would still be stored. There I ran a new build via

gem build rmagick.gemspec

The build succeeded so I think we're getting somewhere. I ran:

gem install rmagick-2.13.1.gem --platform=ruby -- --with-opt-lib=c:\ImageMagick\6.3.5-Q8\lib --with-opt-include=c:\ImageMagick\6.3.5-Q8\include

and got this output (note that I'm no longer getting Invalid Drive but this is otherwise identical to before):

So now I'm just working on why it can't determine the ImageMagick version...

Answer 1

While this may not exactly answer the question... it's likely that as a novice user I borked my installation at some point.

Back-tracking and uninstalling everything that I had previously installed and then following the installation instructions again resolved the issue.

Note that this time around even in parts where it said, "although future versions should also work" I instead specified the exact versions that were mentioned in the article at the time of writing.

Answer 2

ImageMagick is a native library, used by RMagick to manipulate images. It seems something might be wrong with your ImageMagick installation, and RMagick is unable to detect the ImageMagick version installed on your environment.

On the console, when you type 'identify', do you have the output of an application or just an file not found error?

Answer 3

There is an old version of rmagick, though bundler try to install a newer version. The build of the new version went something wrong. You should check the log file to find why.
