推送到 heroku 时出错 - 中止我的佣金资产:预编译 [英] Error pushing to heroku - aborting my rake assets:precompile

问题描述

我是一名新的 ruby​​ on rails 学生.

I'm a new ruby on rails student.

在我的 Git Push Heroku Master 之后，我遇到了 Heroku 的问题.这是最新最好的，中止 rake 资产:预编译.

Following my Git Push Heroku Master, I am running into issues with Heroku. Here is the latest and greatest, aborting the rake assets:precompile.

-----> 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
   Injecting rails31_enable_runtime_asset_compilation
   Please see this article for troubleshooting help:
   http://devcenter.heroku.com/articles/rails31_heroku_cedar#troubleshooting

下面是我的 Gemfile 的内容:

Included below are the contents of my Gemfile:

gem 'rails', '3.2.8'
gem 'bootstrap-sass', '2.1'
gem 'pg'

group :development, :test do
  gem 'rspec-rails'
  gem 'guard-rspec'
  gem 'guard-spork'
  gem 'spork'
  gem 'annotate'
  gem 'database_cleaner'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
end

platforms :jruby do
  gem 'trinidad'
  gem 'jruby-openssl'
end

gem 'jquery-rails'

# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'ruby-debug'

# Bundle the extra gems:
gem 'RedCloth', '~> 4.2.9', :require => 'redcloth'
gem 'ruby-openid', :require => 'openid'
gem 'rack-openid', :require => 'rack/openid'
gem 'aaronh-chronic', :require => 'chronic' # Fixes for 1.9.2
gem 'coderay'
gem 'lesstile'
gem 'formtastic'
gem 'will_paginate', '~> 3.0.2'
gem 'exception_notification', '~> 2.5.2'
gem 'open_id_authentication'

# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
group :test do
  gem 'database_cleaner'
  gem 'cucumber-rails',    :require => false
  gem 'cucumber-websteps', :require => false
  gem 'factory_girl'
  gem 'rspec'
  gem 'nokogiri', '~> 1.5.0'
  gem 'webrat'
end

可能是什么问题?

更新:我使用 --trace 运行了 rake 命令，它警告我失败，因为生产数据库不存在.我创建了数据库，然后再次运行 --trace，这就是我目前被抛出的:

Update: I ran the rake command with --trace, and it had alerted me with a failure because the production database did not exist. I created the database, and ran --trace again, and this is what I'm currently being thrown:

Command failed with status (1): [/usr/local/Cellar/ruby/1.9.3-p286/bin/ruby...]

推荐答案

参见 Heroku Cedar 上的 Rails 3.1+ Asset Pipeline 文章.故障排除部分涵盖了这种确切的场景.

See the Rails 3.1+ Asset Pipeline on Heroku Cedar article. This exact scenario is covered in the Troubleshooting section.

简而言之，您的 Heroku 应用程序在构建(包括资产编译)和运行(您的应用程序可用的地方)之间具有很强的分离性.这与 12-factor 应用程序原则 一致，但这意味着您的应用程序无法访问在构建阶段配置的任何资源——包括数据库——意味着 ActiveRecord 在资产预编译期间不可用.

In short, your Heroku application has a strong separation between building (including asset compilation) and running (where your application becomes available). This is consistent with the 12-factor app principles, but it means that your application cannot access any configured resources during the build phase -- including the database -- meaning ActiveRecord is unavailable during asset precompilation.

您可以在 config/application.rb 中告诉 Rails 在资产编译期间不要引导您的应用程序:

You can tell Rails not to bootstrap your application during asset compilation in config/application.rb:

config.assets.initialize_on_precompile = false

故障排除部分还建议:

如果 rake assets:precompile 仍然不起作用，您可以通过在本地 config/database.yml 中配置一个不存在的数据库并尝试运行 rake assets:precompile.理想情况下，您应该能够在不连接数据库的情况下运行此命令.

If rake assets:precompile is still not working, you can debug this locally by configuring a nonexistent database in your local config/database.yml and attempting to run rake assets:precompile. Ideally you should be able to run this command without connecting to the database.
