ruby-on-rails - 插入 Heroku 时出错(预编译 Assets 失败。)

Question

注意:我使用的是 Rails 3.2.13 和 Ruby“1.9.3”，以及 postgres-0.15.1

我试图按照这个网站的程序将我的 Ruby on Rails 应用程序推送到 heroku http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec-deploying, 但我在尝试推送到 heroku 时出错

   Connecting to database specified by DATABASE_URL
   rake aborted!
   could not connect to server: Connection refused
   Is the server running on host "127.0.0.1" and accepting
   TCP/IP connections on port 5432?

 !     Precompiling assets failed.
 !     Push rejected, failed to compile Ruby app

To git@heroku.com:pure-hamlet-9148.git
 ! [remote rejected] master -> master (pre-receive hook declined)

所以，我自己用谷歌搜索并运行以下命令

heroku labs:disable user-env-compile
heroku labs:enable user-env-compile

仍然出现同样的错误，请帮我解决这个问题。

随着 Simone 的回答，

按照此网站在部署之前在本地预编译您的 Assets 。 https://devcenter.heroku.com/articles/rails-asset-pipeline

RAILS_ENV=production bundle exec rake assets:precompile
git add public/assets -f
git commit -m "vendor compiled assets"
