ruby-on-rails – Rok应用程序在Heroku上失败：(没有路由匹配[GET]“/”)

分类：Ruby作者：编程之家
Newbie到Rails和Heroku,我试图通过遵循 Rails Tutorial中的分步说明来部署一个简单的应用程序.该应用程序在本地运行良好,并显示默认的Rails起始页面.但是,导航到Heroku的应用程序网址不断给我404页面未找到,即使它是相同的应用程序,我没有触及路由文件或任何控制器等.

我在Mac 10.6.8上使用最新的Ruby(1.9.3)和Rails(4.0.0).

我试过的事情

在Rails 3.1.3 on Heroku: (No route matches [GET] “/assets/rails.png”)的答案之后,我添加了config / application.rb的代码,用于在生产中懒洋洋地编译资产：

if defined?(Bundler)
  # If you want your assets lazily compiled in production,use this line
  Bundler.require(:default,:assets,Rails.env)
end

根据Rails production static files routing error的答案,我修改了production.rb,以确保静态资产被提供：

config.serve_static_assets = true

但我还是得到了404.我还能做些什么？

Heroku日志：

解决方法

首先是Rails4应用程序 no longer serve public/index.html或app / assets / rails.png,因为这些文件现在由rails gem本身处理,所以你可以安全地忽略与他们有关的所有谈话.

其次,我建议你忽略你所链接的question中给出的建议,因为它与rails4没有任何关系.如果您使用heroku,则不需要对您的资产进行编译.当您将应用程序推送到他们时,它们会为您做.这可能值得删除您在运行的rake资产时创建的公共/资产文件夹：预编译,因为它会妨碍

第三,删除您添加到config / application.rb的代码,因为有no assets group in Rails 4

第四,heroku用来注入一个插件来为您的应用程序提供静态资源,但是现在您需要通过将以下内容添加到您的Gemfile中来添加到do that yourself：

gem 'rails_log_stdout',github: 'heroku/rails_log_stdout'
gem 'rails3_serve_static_assets',github: 'heroku/rails3_serve_static_assets'

X-4545 X- 200 X- 200 200 X- 200 X- 200 200 X- 200 200： 200新X- 200 200 X- 200 200 X- 200 200 X- 200 200 X- 200 X- 20045 X-

最后,不要担心默认的Rails着陆页不会显示在Heroku上.这可能是他们的系统中的错误,它发生在我身上,这将会发生在下一个人身上,如果他也尝试了,这可能会发生在Matz.这没什么大不了的.新新旗新新新旗新新新旗新新旗旗新新旗旗新新旗新旗旗您的应用程序已准备好开始开发自己的着陆页.

祝你好运,为什么值得,这是一个非常简单的例子Gemfile优化为英雄：

source 'https://rubygems.org'

# you are using Ruby 1.9.3,better to 2.0.0 upgrade for more speed
ruby '2.0.0'

gem 'rails','4.0.0.rc1'    
gem 'sass-rails','~> 4.0.0.rc1'    
gem 'uglifier','>= 1.3.0'
gem 'coffee-rails','~> 4.0.0'
gem 'jquery-rails'
gem 'turbolinks'    
gem 'jbuilder','~> 1.0.1'

# The asset_sync gem is WELL worth using
# but you should read more about it before deciding
# https://github.com/rumblelabs/asset_sync
# gem 'asset_sync'

# only want sqlite in dev and test envs
group :development,:test do
  gem 'sqlite3'
end

group :production do
  gem 'pg' # dont want sqlite in production
  gem 'unicorn' # make sure you follow installation instructions for this gem
  gem 'rails_log_stdout',github: 'heroku/rails_log_stdout'
  gem 'rails3_serve_static_assets',github: 'heroku/rails3_serve_static_assets'
end

group :doc do
  gem 'sdoc',require: false
end
