Question

I have a sample app that is using compass gem including blueprint. I just deployed this app on heroku for the first time and I’m seeing the following error in heroku logs

Errno::EACCES (Permission denied – /app/public/stylesheets/ie.css):

Is there something special required in my rails app that will make this error go away? I’m assuming it’s coming because I’m using the compass gem…

Answer 1

Do a compass compile before deploying to heroku.

Also, in your production.rb, add the following line:

Sass::Plugin.options[:never_update] = true

This will prevent compass from compiling css at runtime (since heroku does not allow writes on filesystem)
