Ruby on Rails教程Heroku应用程序错误
[英]Ruby on Rails Tutorial Heroku application error
问题描述
I am stuck in Michael Hartl's Ruby on Ralis (3rd Edition) on Cloud 9. 
我陷入了Cloud 9上Michael Hartl的Ruby on Ralis（第3版）中。
I have tried to get heroku app working, but I am getting: 我试图让heroku应用程序正常工作，但是我得到了：
Aplication Error
An error occurred in the application and your page could not be served.
If you are the application owner, check your logs for details.
As Chloe suggested I've changed 'sass-rails' version and updated 'sass-rails' 就像克洛伊（Chloe）所建议的那样，我更改了'sass-rails'版本并更新了'sass-rails'
Gemfile now: 现在的Gemfile：
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
As thesecretmaster advised I've migrated from sqlite3 to postgesql using the instructions given by heroku 正如secretmaster所建议的那样，我已经按照heroku 给出的说明从sqlite3迁移到了postgesql 。
bundle install: 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.

It's best to close one question and ask another question to keep the problems separate. 最好关闭一个问题，再问另一个问题，以使问题分开。 Your new error is 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)
It looks like you didn't run Bundler, because you are still using 5.0.1. 您似乎没有运行Bundler，因为您仍在使用5.0.1。 It's probably an error in the Sass gem. 这可能是Sass gem中的错误。 Try to use an older version or newer version of the gem. 尝试使用旧版本或较新版本的gem。 See which versions you have installed locally. 查看您在本地安装了哪些版本。
gem list sass-rails
Try to update to the latest gem. 尝试更新到最新的宝石。 I have 5.0.3 and the latest now is 5.0.4. 我有5.0.3，最新的是5.0.4。 Remove the version from your Gemfile and run 从您的Gemfile中删除版本并运行
bundle update

If everything is working fine locally I would run: 如果在本地一切正常，我将运行：
heroku logs --tail
from your terminal and then reload the page. 从您的终端，然后重新加载页面。 If you look in the logs you should get a better understanding of what exactly the error is. 如果您查看日志，则应该更好地了解错误的确切含义。

Your problem is that heroku hates sqlite3 (read: doesn't support and doesn't allow you to have the gem in your app). 您的问题是heroku讨厌sqlite3 （阅读：不支持，并且不允许您在应用程序中使用gem）。 Here is what they have to say https://devcenter.heroku.com/articles/sqlite3 . 这就是他们不得不说的https://devcenter.heroku.com/articles/sqlite3 。 Instead I would migrate to postgesql. 相反，我将迁移到postgesql。 It doesn't make any difference in how your app will run, and your won't notice anything after you switch. 这对您的应用程序的运行方式没有任何影响，切换后您将不会注意到任何东西。 I use heroku postgres for my databases. 我将heroku postgres用于我的数据库。 To migrate you should just follow the instruction in the article I linked above. 要进行迁移，您应该按照上面我链接的文章中的说明进行操作。 Good Luck! 祝好运！
You can also get out of terminal without closing the window by pressing CTRL+C 您也可以通过按CTRL+C退出终端而不关闭窗口
update 1 更新1
To solve your sass error you can use this question . 为了解决您的sass错误，您可以使用这个问题 。 Apparently it is an issue with sass 5.0.1, so you just need to update the gem. 显然，这是sass 5.0.1的问题，因此您只需要更新gem。
update 2 更新2
Gems not updating in cloud nine could have something to do with the answer to this answer . 没有在云九中更新的宝石可能与该答案的答案有关 。 I Don't know much about cloud nine, sorry. 抱歉，我对云九了解不多。
