Permission denied in tmp

Question

I just deployed a Rails 3 app with Ruby 1.9.2. I have been getting several errors.

1. application.css wasn\'t compiled. so I set pre compilation in <

Answer 1

I think a better solution without giving everyone manage rights to tmp folder is like that:

 sudo rake tmp:cache:clear

This will clear the temp folder and when you run rails server again it won't give error.
