Paperclip 2.3.5中的错误重新处理

Question

I updated from 2.3.3 to 2.3.5 for the string to array bug, and now when I try to call Model.image.reprocess! I get the following error. Is this something in my code or something in paperclip? Or maybe in the image I'm uploading?

Answer 1

It's a bug with paperclip . Revert to the previous version and you'll be fine. This really had me pulling my hair out for a few days as well. :)

Answer 2

Not an answer, just confirming I have the same issue. I'm on Rails 3 and have tried using Paperclip 2.3.5, 2.3.4 and 2.3.3 All to no avail keep getting the same error as @Reactor5 when invoking reprocess

Any ideas?

EDIT I looked into this some more. It seems to be an issue with Paperclip and Ruby 1.9.2 Still don't know exactly what causes it, but switching to Ruby 1.8.7 solved the issue for me.
