Rails Server引发错误“无法加载此类文件” — sass / logger（LoadError）

Question

Rails: 3.2.12 Ruby: 1.9.3p392 (openSuse package) OS: openSuse 12.3

I just ran rails new specsheets . This ran cleanly including the bundle install:

Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.

When I attempt to start the WEBrick server it throws the following at me:

I'm new to rails so I don't know what to look for. In the past I'd go to the directory in question (/usr/lib/ruby/gems/1.9.1/gems/) and make sure everything was readable by non-root users and groups. This hasn't worked this time around.

I also noticed that my Gemfile mentioned sass-rails 3.2.3 while the installed version is 3.2.6. I modified the Gemfile to reflect this but still get the errors.

My Gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.12'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'


# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.6'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'debugger'

The log directory under the application directory is empty so there is nothing to report from there.

The server starts fine when run with sudo . However, as I have this in my own /home directory that shouldn't be the case.

Put sass-rails above rails in your gemfile.

The sass-rails gem is trying to setup the logger and cannot find the Sass::Rails::Logger class. https://github.com/rails/sass-rails/blob/3-2-stable/lib/sass/rails/railtie.rb#L23

This is probably because you are calling sass before it has time to setup and autoload. https://github.com/rails/sass-rails/blob/3-2-stable/lib/sass/rails.rb#L7
