我只是在Heroku的制作中遇到“出错了”500错误，并且仅针对我的一个几乎完全没有动态内容的页面。
在日志中，它显示以下内容：
ActionView::MissingTemplate (Missing template pages/contact, application/contact with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :coffee, :haml]}. Searched in:
2013-03-28T03:42:28+00:00 app[web.1]: * "/app/app/views"
2013-03-28T03:42:28+00:00 app[web.1]:
但是，模板肯定是在那个位置。 Heroku运行rake路线显示正确的路线。我按照其他论坛的建议，将uglifier，coffeescript和haml-rails从我的gemfile的资产组中移出。 Gemfile现在看起来像这样：
source 'http://rubygems.org'
gem 'mail'
gem 'rails', '3.2.13'
gem 'pg'
gem 'twitter'
gem 'jquery-rails'
gem 'rake', '10.0.4'
gem 'sass', "~> 3.2.7"
gem 'haml-rails'
gem 'coffee-rails'
gem 'uglifier'
gem 'therubyracer'
gem 'sass-rails'
group :development do
gem 'rspec-rails'
gem 'annotate'
gem 'faker', '0.3.1'
end
group :test do

end
# Bundle edge Rails instead:

# Use unicorn as the web server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+)
# gem 'ruby-debug'
# gem 'ruby-debug19', :require => 'ruby-debug'
# Bundle the extra gems:
# gem 'bj'
# gem 'nokogiri'
# gem 'aws-s3', :require => 'aws/s3'
# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
# group :development, :test do
# gem 'webrat'
# end
# 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'
我没有在日志或其他Stack Overflow问题中看到任何有用的内容。那里有新鲜的眼睛看到我不知道的东西？

要确认contact.html.erb是否已将其发送至Heroku，请尝试运行以下命令：
heroku run bash
cat app/views/pages/contact.html.erb

在放弃之前，我决定采用一种非常奇怪的冰雹玛丽预感来解决问题。
我将有问题的文件“contact.html.erb”，“contact.css.erb”复制并粘贴到名为“contacto.html.erb”等的新镜像文件中，代替“联系人”。
将路线更改为：match'/ contact'=＆gt; 'pages＃contacto'并推送到heroku。错误消失了。更令人惊讶的是，在我删除原件并用“联系人”代替contacto重命名那些相同的文件后，它仍然有用。
我真的不明白这项工作背后的伏都教是什么。我本来只是尝试路由解决方法。我甚至先删除了那些“联系”文件中的所有内容并将它们推送到heroku，替换了所有内容并再次推送它们，没有任何改动。
