我有一个现有的heroku rails 4应用程序( https://applicantlabs.herokuapp.com/)在本地运行时看起来是正确的，但是当我在heroku上运行时，造型是破碎的。

我的gemfile看起来像这样

@H_403_4@source 'https://rubygems.org' ruby "2.2.1" gem 'rails','4.2.1' gem 'pg' gem 'uglifier','>= 1.3.0' gem 'jquery-rails' gem 'devise' gem 'devise-bootstrap-views' gem "twitter-bootstrap-rails" gem 'rails_12factor',group: :production # for heroku gem 'puma' gem 'sucker_punch'

我试图通过将这个添加到config / environments / production.rb文件然后部署来解决这个问题

@H_403_4@config.assets.compile = true

我也试过

@H_403_4@bundle exec rake assets:precompile

然后提交并推送。

没有任何工作。

css文件被添加到app / assets / stylesheets中

然后在app / assets / stylesheets / application.css我有

@H_403_4@/* *= require animate.min *= require bootstrap_and_overrides *= require font-awesome *= require_self */ body{padding:0;margin:0;font-family:'Open Sans','Trebuchet MS',arial,sans-serif;font-size:13px}

当我查看页面的源码并单击css文件时，它将填充奇怪的文本。这里有一点点：

@H_403_4@book����mark����8���8���ìS���

当我推到heroku的输出是：

@H_403_4@bundle exec rake assets:precompile RAILS_ENV=production

输出是
