Rails 应用程序未在 Heroku 上运行 [关闭]

【问题标题】：Rails application not running on Heroku [closed]Rails 应用程序未在 Heroku 上运行 [关闭]
【发布时间】：2014-01-09 13:48:51
【问题描述】：

我使用的是 Ruby 1.9 版和 Rails 3.2 版

我已将其包含在我的 gemfile 中（按照 Micheal Hartl 在他的书中的指示）

group :production do
  gem 'pg', '0.15.1'
  gem 'rails_12factor', '0.0.2'
end

我的 repo 在我的本地服务器上运行良好，我也可以在 Heroku 上成功部署它（例如，它没有显示任何错误）但是当我尝试在 Heroku 上打开它时，它说发生了一些错误.

Heroku 链接：

我的 Github 仓库：

如何让我的 rails 应用程序在 Heroku 上运行？

【问题讨论】：

  • 你迁移数据库和预编译资产了吗？
  • 我看到了你的Gemfile，请在本地控制台发出bundle install --without=test,development
  • 所以你先git add .，然后bundle install？执行以下操作。 1. bundle install --without=test,development 并确保它没有错误通过，2. 问题bundle install，3. 问题git add .； 4. 发布git add -f Gemfile.lock 5. 提交更改 6. 发布推送到heroku。
  • 我没有看到 You have activated Rake 10.1.1 but your Gemfile requires 10.1.0 错误...你能显示 heroku 推送日志吗？
  • 预编译错误提到了screen.css，但我在编译日志的已编译资产列表中没有看到这一点。 CSS 文件可能没有包含在预编译中，如果您在开发中编译资产，您可能不会在本地注意到这一点。因此，它在生产环境中中断，但在其他地方没有。检查您的 config/environments/ 文件夹，并比较开发与生产的各种 config.assets 选项。

【解决方案1】：

首先将您的blueprint 目录移动到assets/stylesheets 目录中。

添加到环境/production.rb 

config.assets.precompile += %w( blueprint/screen.css blueprint/print.css blueprint/ie.css custom.css)

如果你愿意，你可以在本地预编译你的资产：

bundle exec rake assets:precompile RAILS_ENV=production

【讨论】：

  • 啊……终于成功了。非常感谢 :) 两个问题供将来参考： 1>我应该将 blueprint/bootstrap 或任何其他 css 框架放入 assets/stylesheets 目录而不是教程建议的 public 文件夹吗？ 2> 每次推送到heroku之前，我需要预编译我的资产吗？
  • 是的，把你所有的 css/javascripts 放到你的 assets 目录是一个很好的做法。查看guides.rubyonrails.org/asset_pipeline.html 以更好地使用资产管道。
  • 在 production.rb 中 config.assets.compile 设置为 false，所以你需要在推送 heroku 之前进行预编译。
  • 如果我将值设为 true，它是否会在不预编译的情况下工作或导致其他地方出现问题？
