我最近将这个部署到我的heroku服务器上，用于我正在进行的rails项目。它在localhost：3000中工作100％，当我把它放在服务器上时，整个事情都被打破了，并且不会加载我在routes.rb文件中设置的页面。我把它设置正确，我希望它能有效，直到我上传它。任何帮助将不胜感激，如果您需要查看任何代码，请询问。
请记住，我正确地完成了gem 'pg'，因为我安装并上传没问题。
再次感谢你们！

答案 0 :(得分：0)
根据Rails Guides，资产组下的宝石不包含在生产组中。这是指南所说的部分：
# 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
如果您将资产组与Bundler一起使用，请确保您的 config / application.rb具有以下Bundler require语句：
if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
Bundler.require *Rails.groups(:assets => %w(development test))
# If you want your assets lazily compiled in production, use this line
# Bundler.require(:default, :assets, Rails.env)
end
对于您的情况，您需要将production添加到需要资产组的环境列表中：
if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
Bundler.require *Rails.groups(:assets => %w(development test production))
# If you want your assets lazily compiled in production, use this line
# Bundler.require(:default, :assets, Rails.env)
end
或者，您也可以使用注释掉的代码：
if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
# Bundler.require *Rails.groups(:assets => %w(development test production))
# If you want your assets lazily compiled in production, use this line
Bundler.require(:default, :assets, Rails.env)
end
