在发帖时，没有格式化下面的代码，显示不全面，重新编辑再发。

在 update 时报错：

joinall@nxbbs-server:/nxbbs/bbs$ which convert /usr/local/bin/convert 在 development.rb 里已经加代码： Paperclip.options[:command_path] = "/usr/local/bin/"

identify 命令结果应该也正常 joinall@nxbbs-server:/nxbbs$ convert logo: kala.jpg joinall@nxbbs-server:/nxbbs$ identify kala.jpg kala.jpg GIF 640x480 640x480+0+0 8-bit sRGB 256c 31.7KB 0.000u 0:00.000
