mongoid-Paperclipでimagemagick関連のエラーが出たら.
 https://github.com/meskyanichi/mongoid-paperclip
を使ったところ、ログにエラーが出た.
[paperclip] An error was received while processing: #<Paperclip::Errors::CommandNotFoundError: Could not run the `identify` command. Please install ImageMagick.>

http://stackoverflow.com/questions/6687312/how-to-install-imagemagick-for-use-with-rvm

install_imagemagick.sh

#!/bin/bash
mkdir
-p ~/local
command -v identify > /
dev/null
if [ $? -eq 1 ]; then
    echo
"${bldgrn}Installing imagemagick into ${txtwht}$HOME/local/imagemagick${txtrst}"
    wget
-N --retr-symlinks ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz
    tar
-xzvf ImageMagick.tar.gz
    cd
ImageMagick-*
   
./configure --prefix=$HOME/local/imagemagick
    make
    make install
    cd
..
    rm
-rf ImageMagick-*
fi
インストールして、pathも入れる.

Then I add this to my ~/.bashrc or ~/.zshrc

export PATH=$HOME/local/imagemagick/bin:$PATH
export LD_LIBRARY_PATH
=$HOME/local/imagemagick/lib:$LD_LIBRARY_PATH

インストールしてもエラー
[paperclip] An error was received while processing: #<Paperclip::Errors::NotIdentifiedByImageMagickError: /tmp/p131985945074DTFdik20120513-18764-1k7hngf.JPG is not recognized by the 'identify' command.>

その場合は、パスをdevelopment.rbに入れる
