Permission denied - /tmp/.ruby_inline/Inline_ImageScience_cdab.c

I have a Ruby on Rails app that I've recently deployed to a remote server (Ubuntu 9.10, nginx, passenger, ruby-enterprise) and I'm getting the error (works fine locally):

Permission denied - /var/www/project_name/tmp/.ruby_inline/Inline_ImageScience_cdab.c

First, the fol开发者_StackOverflowder /tmp/.ruby_inline/ is empty - should it be? Is it trying to create Inline_ImageScience_cdab.c or read it?

I think I have all the required gems installed: 'gem list' shows image_science and RubyInline installed. libfreeimage3 and libfreeimage-dev are also installed.

I've run chmod 755 on /tmp/.ruby_inline/ to match the permissions on surrounding folders but I cannot go any higher than that, however, or I get another error:

/var/www/project_name/tmp/.ruby_inline is insecure (40777). It may not be group or world writable. Exiting.

And I guess second, why am I getting this error? :)

Thanks

I was able to fix the problem. The folder /tmp/.ruby_inline/ wasn't supposed to be empty so it wasn't finding Inline_ImageScience_cdab.c and giving a 'permission denied'. The files required were installed to ~/.ruby_inline so I just copied them to /tmp/.ruby_inline and chmod 755 them.

also i guess the filesystem in the production is for some reason read-only to store static content. Contact your host.
