You need to change the files production.rband development.rbwhich are in:
您需要更改文件production.rb，development.rb哪些文件位于：
config/environments:
配置/环境：
# Paperclip config:
Paperclip.options[:image_magick_path] = "/opt/ImageMagick/bin"
Paperclip.options[:command_path] = "/opt/ImageMagick/bin"
Just add those two lines just before the last line and restart the server.
只需在最后一行之前添加这两行并重新启动服务器。
In MacOSX system, if you are using another location, just put the right PATH there.
在 MacOSX 系统中，如果您使用其他位置，只需将正确的 PATH 放在那里。

You can type
你可以输入
which convertand which identify
which convert和 which identify
to check whether imagemagick is installed properly.
检查 imagemagick 是否安装正确。
In my case, which convertreturns /usr/local/bin/convertbut identify not found.
就我而言，which convert返回/usr/local/bin/convert但identify not found.
I used brew install imagemagickbefore, so I run it again and return imagemagick already installed, it's just not linked.
我brew install imagemagick以前用过，所以我再次运行它并返回imagemagick already installed, it's just not linked。
Finally got the point, brew link imagemagick(or brew link --overwrite imagemagick)
终于明白了，brew link imagemagick（或brew link --overwrite imagemagick）
Don't forget to add the Paperclip.options[:command_path] = "/usr/local/bin/"to your config/environment.rbfile.
不要忘记将Paperclip.options[:command_path] = "/usr/local/bin/"加到您的config/environment.rb文件中。

I had this issue, when I had started rails server from my rubymine ide. It seems it does not load your .zshrc (in my case, could also be valid for .bashrc). So some environment variables that make imagemagick work with dvm were not set. For example:
当我从我的 rubymine ide 启动 rails 服务器时，我遇到了这个问题。它似乎没有加载您的 .zshrc（在我的情况下，也可能对 .bashrc 有效）。所以一些使 imagemagick 与 dvm 一起工作的环境变量没有设置。例如：
export PATH=$HOME/local/imagemagick/bin:$PATH
export LD_LIBRARY_PATH=$HOME/local/imagemagick/lib:$LD_LIBRARY_PATH
Once I restarted from my terminal, the error was gone.
一旦我从终端重新启动，错误就消失了。
