即使命令行显示已安装，Rails也无法找到Idenfity（ImageMagick）

Question

If I run identify -version no the command line I get:

Version: ImageMagick 6.7.4-2 2012-01-04 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC
Features: OpenMP  

But my rails app gives the following whenever I submit a form (which makes a thumbnail out of an uploaded image):

Could Not Run The `Identify` Command. Please Install ImageMagick.

Any advice would be greatly appreciated!

This is what my .bash_profile has:

PATH=$PATH:$HOME/bin:/usr/sbin:/sbin/:/usr/bin:$HOME/.rvm
export PATH=$HOME/local/imagemagick/bin:$PATH
export LD_LIBRARY_PATH=$HOME/local/imagemagick/lib:$LD_LIBRARY_PATH

My production.rb has the correct config for PaperClip as well:

Paperclip.options[:command_path] = "/usr/local/bin"

I think imagemagick is looking in Path, not PATH. forget your .bash_profile, set it in your script:

ENV['Path'] = '/path/to/ImageMagick/bin'
