Answer 1

检查您的 /config/enviroments/production.rb（或开发）文件并为 ImageMagick 设置转换命令路径。

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

Answer 2

I got the same error message when I tried to assign attachment this way:

file = new Tempfile("image.png")    
user.image = file

It worked after I changed it to this:

user.image = File.open("image.png")

If this wasn't your case, you should give a little more information about your problem.
