过去两天我一直在工作（似乎还不够长）来haml-rails开始使用这个 RoR 应用程序。我得到的回溯是这样的：
ActionView::MissingTemplate (Missing template customcare360/login, application/login with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder]}. Searched in:

我已经尝试手动将“haml-rails”加载到我的config/application.rb. 我的 Gemfile 看起来像这样：
source 'https://rubygems.org'
gem 'rails', '3.2.11'
# Environment-independent gems
gem 'mysql2'
gem 'json'
# Use unicorn as the app server
gem 'unicorn'
# HAML up the HTML.
gem 'haml'
gem 'haml-rails'
group :development do
# Provides an intuitve means of debugging in the browser.
gem 'better_errors'
# Remove unnecessary assets from being logged at dev time.
gem 'quiet_assets'
# Deploy with Capistrano
gem 'capistrano'
gem 'capistrano-ext'
gem 'capistrano-unicorn'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'uglifier', '>= 1.0.3'
gem 'jquery-rails'
end
