【问题描述】：
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 上运行它时，样式被破坏了。
我的 gemfile 看起来像这样
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'
我尝试通过将其添加到 config/environments/production.rb 文件然后部署来解决问题
config.assets.compile = true
我也试过
bundle exec rake assets:precompile
然后提交并推送。
没有任何效果。
css文件添加到app/assets/stylesheets
然后在app/assets/stylesheets/application.css我有
/*
*= 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}
当我查看页面的源代码并单击 css 文件时，它充满了奇怪的文本。这是其中的一小部分：
book����mark����8���8���ìS���
当我推送到 heroku 时，输出是：
