我有一个正在尝试部署到 Heroku 的雪松堆栈的应用程序。
在部署的预编译阶段，我收到错误消息：
Your bundle is complete! It was installed into ./vendor/bundle
Cleaning up the bundler cache.
-----> Writing config/database.yml to read from DATABASE_URL
-----> Preparing app for Rails asset pipeline
Running: rake assets:precompile
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?
Tasks: TOP => environment
(See full trace by running task with --trace)
Precompiling assets failed, enabling runtime asset compilation
通常我可以通过添加来解决这个问题
config.assets.initialize_on_precompile = false
如Heroku 文档config/initializers/production.rb中所述。
不过，这一次似乎并没有解决问题。我还能尝试什么？
这是我的 Gemfile：
