我用一个简单的带有索引函数的页面控制器做了一个基本的rails应用程序，当我加载页面时，我得到:
ActionView::Template::Error (application.css isn't precompiled):
2: <html>
3: <head>
4: <title>Demo</title>
5: <%= stylesheet_link_tag "application" %>
6: <%= javascript_include_tag "application" %>
7: <%= csrf_meta_tags %>
8: </head>
app/views/layouts/application.html.erb:5:in `_app_views_layouts_application_html_erb__43625033_88530400'
Gemfile
source 'http://rubygems.org'
gem 'rails', '3.1.0'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
gem 'execjs'
gem 'therubyracer'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', " ~> 3.1.0"
gem 'coffee-rails', "~> 3.1.0"
gem 'uglifier'
end
gem 'jquery-rails'
# Use unicorn as the web server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'
group :test do
# Pretty printed test output
gem 'turn', :require => false
end
