Heroku推送错误资产预编译端口错误

Question

我无法推送到heroku。

这是我的heroku日志http://pastebin.com/M7q7qJ3x

错误发生在这里

-----> 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?

这是我的database.yml文件

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
development:
  adapter: postgresql
  encoding: unicode
  database: restaurant_development
  pool: 5
  username: judyngai
  password:
  host: localhost

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: postgresql
  encoding: unicode
  database: restaurant_test
  pool: 5
  username: judyngai
  password:
  host: localhost

production:
  adapter: postgresql
  encoding: unicode
  database: restaurant_production
  pool: 5
  username: judyngai
  password:
  host: localhost

我应该将主机更改为“127.0.0.1”并添加一个端口吗？ 这很奇怪。我不明白这一点。

这是另一个错误

Precompiling assets failed, enabling runtime asset compilation

我根本没碰过js，css文件。

在推送之前，我应该在本地“编译资产”吗？我对资产不太熟悉。

Answer 1

在application.rb或production.rb添加

中的配置中

config.assets.initialize_on_precompile = true

Answer 2

的Gemfile

添加此

gem 'sass', '3.2.13'

它为我工作。
