Ruby on Rails的教程的Heroku应用程序错误

Question

我被困在迈克尔·哈特尔的Ruby上Ralis（第3版）云9

我试图让Heroku的应用程序的工作，但我正在逐渐：

应用程序错误

在应用程序中发生错误，并且您的页面不能以 提供服务。请稍后重试。

如果您是应用程序所有者，请查看您的日志以了解详细信息。

由于Chloe的建议我已经改变了'青菜-Rails的版本和更新的 '青菜护栏'

的Gemfile现在：

source 'https://rubygems.org' 

    gem 'rails', '4.2.0' 
    gem 'sass-rails', '5.0.3' 
    gem 'uglifier', '2.5.3' 
    gem 'coffee-rails', '4.1.0' 
    gem 'jquery-rails', '4.0.3' 
    gem 'turbolinks', '2.3.0' 
    gem 'jbuilder', '2.2.3' 
    gem 'sdoc', '0.4.0', group: :doc 

    group :development, :test do 
     gem 'pg', '0.17.1' 
     gem 'byebug', '3.4.0' 
     gem 'web-console', '2.0.0.beta3' 
     gem 'spring', '1.1.3' 
    end 

    group :production do 
     gem 'pg', '0.17.1' 
     gem 'rails_12factor', '0.0.2' 
    end 

由于thesecretmaster劝我从sqlite3的迁移到postgesql使用the instructions given by heroku

捆绑安装：

Your Gemfile lists the gem pg (= 0.17.1) more than once. 
You should probably keep only one of them. 
While it's not a problem now, it could cause errors if you change the version of just one of them later.

在heroku install我看到我有青菜护栏5.0.3，但在heroku logs它仍然是5.0.1。

$ heroku open：

Answer 1

如果一切正常本地我会跑：

heroku logs --tail 

从终端，然后重新加载页面。如果你查看日志，你应该更好地理解错误是什么。

Answer 2

你的问题是，heroku讨厌sqlite3（阅读：不支持，不允许你在你的应用程序中有宝石）。这是他们不得不说的https://devcenter.heroku.com/articles/sqlite3。相反，我会迁移到postgesql。它不会在您的应用程序运行方式上发生任何变化，您切换后不会注意到任何内容。我为我的数据库使用了heroku postgres。迁移你应该只是按照我上面链接的文章中的说明。祝你好运！

你也可以摆脱终端的不按CTRL+C

更新1

解决您的sass错误，您可以使用this question关闭窗口。显然这是sass 5.0.1的一个问题，所以你只需要更新宝石。

更新2

宝石在九霄云外不更新可能有事情做与答案this answer。我对云九不太了解，对不起。

Answer 3

最好是关闭一个问题，问另一个问题以保持问题分离。您的新错误是

/app/vendor/bundle/ruby/2.0.0/gems/sass-rails-5.0.1/lib/sass/rails/helpers.rb:11:in '<top (required)>': uninitialized constant Sass::Script (NameError) 

看起来您没有运行Bundler，因为您仍在使用5.0.1。这可能是Sass宝石中的一个错误。尝试使用旧版本或更新版本的宝石。查看您在本地安装的版本。

gem list sass-rails 

尝试更新到最新的gem。我有5.0.3，现在最新的是5.0.4。从Gemfile中删除版本并运行

bundle update
