我的应用程序在我的本地服务器上运行，但是当我将它上传到 Heroku 时，我得到一个页面，上面写着："We're sorry, but something went wrong."

当我查看 Heroku 日志时，我看到一条错误行：

ActionView::Template::Error (/app/app/assets/stylesheets/application.css has already been required)

如果我的应用程序在我的本地环境中运行良好，这意味着什么？有关如何解决此问题的任何建议？

对于它的价值，我的 gemfile 看起来像这样：

source 'https://rubygems.org'

gem 'rails', '3.2.8'
gem 'bootstrap-sass'
gem 'bcrypt-ruby', '3.0.1'
gem 'json'
gem 'ruby-fs-stack'


group :development, :test do
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails', '2.11.0'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '3.2.5'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier',     '1.2.3'
end

gem 'jquery-rails', '2.0.2'

group :test do
  gem 'capybara', '1.1.2'
  gem 'factory_girl_rails', '4.1.0'
end

group :production do
  gem 'pg', '0.12.2'
end

这是 Heroku 日志：

我不知道它为什么在 localhost 上工作，但似乎你有一个循环依赖。

转到 app/assets/stylesheets 并检查 application.css.scss 的标头，然后检查它所需的所有文件的标头，以确保它们都没有引用 application.css.scss。
