问题
I'm working on developing a refinerycms rails app that was working good locally and now i've moved it to my VPS and I was having issues with images that i uploaded through refinerycms not loading and i've been reading that i needed to upgrade my version of imagemagick. I upgraded from 6.2.8 to 6.7.8. Now the images all load on some pages, but not on the admin side.
What is causing this issue? Here's the stacktrace of the error.

UPDATE
I've added the code below to my config/application.rb file as suggested here and it helped some of the files show up, and but i'm still unable to upload a file through the app and part of this stacktrace is shown below.
config/application.rb contains this
initializer 'override-image-magick-paths', :after => 'attach-refinery-images-with-
dragonfly' do
app=Dragonfly[:refinery_images]
app.configure_with(:imagemagick)
app.configure do |c|
c.convert_command = "/usr/local/bin/convert" # defaults to "convert"
c.identify_command = "/usr/local/bin/identify" # defaults to "identify"
end
end

回答1:
I simply reinstalled imagemagick and it worked.
回答2:
I created a symbolic link from /usr/bin/convert -> /usr/local/bin/convert and from /usr/bin/identify -> /usr/local/bin/identify and that seemed to solve my problems.
$ cd /usr/bin
$ ln -s /usr/local/bin/convert convert
$ ln -s /usr/local/bin/identify identify
I'm assuming that dragonfly is still not picking up my location of convert and identify even though i specified it in my config/application.rb file.
回答3:
You may have to provide the full path to convert:
config/initializers/dragonfly.rb:
app.configure do |c|
c.convert_command = "/usr/bin/convert"
end
Change /usr/bin/convert to the correct path to convert, which you can find out by running whereis convert on your VPS shell.
More details in the documentation.
回答4:
Try installing the refinery-images gem:
Gemfile:
gem 'refinerycms-page-images', '~>1.0.3' //refinery v1 compatible (v2 available also)
Then in your model:
belongs_to :imagesizeyouwant, :class_name => 'Image'
If you look at the Image class you'll see a pretty nice set up for handling images. You can add image sizes in Refinery's Settings page in the admin tool. If you have a custom engine, just change :imagesizeyouwant to that size (mine was :thumbnail).
When you post the image, look at the output of the identify command and try to run it on your own. Chances are your system has different parameters it uses for ImageMagick binaries, or that the dimensions being sent to it are not understood. Try posting the output of the actual command Dragonfly is calling in the shell so we can take a better look.
