Hi,

I am using paperclip to attach documents to my models. it works  
perfectly on my dev machine, but on the server I get a  
CommandNotFoundError.

On my server if I ./script/console I can run imagemagick through  
system(“convert”) and it works, so why can’t paperclip find it?

Thanks for your ideas

PS: the paperclip google group isn’t getting much answers so I am  
posting here.

Chances are the _web server_ is running under a user id other than  
yours, and so has a different $PATH.

I’ll also add this: [Equivalent of Apache's SetEnv Variable - NGINX - Ruby-Forum](http://www.ruby-forum.com/topic/214031)

I’m running Nginx+Passenger, and it seems there are issues with  
ImageMagick.

Interesting, and I think you are right.

However the problem might be similar to these:

Simply adding Paperclip.options[:command\_path] fixed the issue, but I  
swear I tried it yesterday!
