Rails CSS not loading with Ruby 2.0

Question

I am having an issue with loading CSS in my Rails app. I have pulled the same repository on two machines.

On one machine, the CSS file is loaded correctly. When I go to a page on this machine, I get the following in my terminal:

Started GET "/" for 127.0.0.1 at 2013-03-06 19:03:32 -0500

  Rendered home/show.html.erb within layouts/application (2088.1ms)
Completed 200 OK in 2114ms (Views: 2104.9ms | ActiveRecord: 8.3ms)

When I load the same page on another machine, I get the following in the terminal

Started GET "/" for 127.0.0.1 at 2013-03-06 19:31:19 -0500
Processing by HomeController#show as HTML
  User Load (0.3ms)  SELECT "users".* FROM "users" WHERE "users"."id" = 460 LIMIT 1
  Rendered layouts/_header.html.erb (3.4ms)
  Rendered home/show.html.erb within layouts/application (5.8ms)
Completed 200 OK in 11ms (Views: 10.7ms | ActiveRecord: 0.3ms)

But none of the CSS compiles. It also doesn't show up in the browser. What could be the problem?

UPDATE: I ran rake assets:precompile on the second machine and it worked. However, deleting the public/assets folder stopped it from working. This means it was not live compiling. Any idea why?

Answer 1

whats the content of you config/environments/development.rb

sepcifically --.

config.assets.compile = false/true ?

Answer 2

I noticed some issues related to assets in ruby 2.0 as well, ie, Applications running in 1.9.3 without problems having CSS issues.

Could you try to see if this helps:

Add to your Gemfile:

gem 'sprockets', '~> 2.9.0'

Then bundle install and try again...

Answer 3

Is the second machine running in the production environment? The CSS is only compiled in development.
