rails paperclip and passenger `is not recognized by the 'identify' command`

Question

When I upload a photo, my model fails validation, err well even without any validations I\'m returned this error:

/tmp/stream20100103-13830-ywmerx-0 is not r         


        

Answer 1

This happened to me when I upgraded OS X to Lion.

Solved it by...

• do a brew list to see all packages you have and save this somewhere

• uninstalling homebrew (see 'Uninstallation' on this page https://github.com/mxcl/homebrew/wiki/Installation )

• reinstall homebrew with the usual

  ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"

• reinstalling all packages brew install ghostscript brew install imagemagick etc for any others you have

Note, before ghostscript would reinstall I had to apply the suggestion found here: https://github.com/mxcl/homebrew/issues/6381

brew edit ghostscript

Then add the def patches block to the bottom of the Ghostscript class:

class Ghostscript < Formula
    .... existing code here ....

    def patches
        { :p0 => 'http://ftp.netbsd.org/pub/NetBSD/packages/pkgsrc/print/ghostscript/patches/patch-ak' }
    end
end 

The above patch may be merged in by the time you read this.

After that imagemagick detected jpegs correctly again.

TL;DR completely uninstall and reinstall homebrew, ghostscript (with patch for Lion), and imagemagick
