服务器上的500内部服务器错误，在本地工作

Question

当所有production.log都给我时，如何追踪错误？

11:  <%= javascript_include_tag "application" %> 
12:  <%= csrf_meta_tags %> 
13:  <%= yield(:head) %> 
app/views/layouts/application.html.erb:10:in `_app_views_layouts_application_html_erb__4417234491726047977_45250520' 
app/controllers/docs_controller.rb:27:in `index' 
Processing by ErrorsController#broken as HTML 
Rendered errors/broken.html.erb within layouts/application (0.5ms) 
Completed 500 Internal Server Error in 16ms 

FYI：行10 application.html.erb是<%= stylesheet_link_tag "application", :media => "all" %>所以我假设它是与我的任何CSS或我的Gemfile。我如何进一步调查？

而且，我的Gemfile：

source 'https://rubygems.org' 

gem 'rails', '3.2.12' 
gem 'json', '1.7.7' 
gem 'mysql2' 

group :assets do 
    gem 'coffee-rails' 
end 

group :development do 
    gem 'better_errors' 
    gem 'binding_of_caller' 
    gem 'meta_request' 
end 

group :development, :test do 
    gem 'rspec-rails' 
    gem 'steak' 
    gem 'factory_girl_rails' 
end

我的Gemfile需要uglifier，这是一个老版本的另一颗宝石的进口。

gem 'uglifier' 

固定它。
