应用样式时回形针失败 - ImageMagick 已安装 - Win 7 - Rails -

Question

I've got paperclip working so that I can upload and edit a photo but when I try to apply styles to it it falls over.

 Invalid argument - convert

ImageMagick is installed but I'm not sure if it's installed properly - when I tested the install with the convert logo: logo.gif it creates the logo but I have to open it from explorer - it won't let me from the command line - as per instructions. (I'm not sure if this is an issue?)

  # Paperclip
    has_attached_file :photo, :styles => { :thumb => "150x115>" }

If I rename the the ImageMagick folder I get a different error undefined method "exitstatus" which suggests to me that paperclip is talking to it but there's another issue?

Got it!!

Not sure what was going on but a system reboot sorted it. I suspect it had something to do with ImageMagick setting it's root path. I had re-installed it several times trying to get it to work.

I don't have Windows 7, but can definitely confirm that it has to do with the installation of ImageMagick, and nothing to do with how you've used the paperclip gem.

Once ImageMagick is installed correctly, you should be able to run the convert command from Cygwin.

Did you run the installer from here ?
