Ruby on Rails Tutorial Heroku Deployment Issue
我已经开始了Ruby on Rails教程,在这里找到:
https://www.railstutorial.org/book/beging sec部署
我正在使用Cloud9在线IDE并尝试在Heroku上部署我的Hello World应用程序,但当我尝试打开该应用程序时,收到以下错误:
An error occurred in the application and your page could not be
served. Please try again in a few moments.If you are the application
owner, check your logs for details.

根据日志显示,Postgres PG GEM似乎有问题。这是GemFile:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | source 'https://rubygems.org' gem 'rails', '4.2.2' gem 'sass-rails', '5.0.2' 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 'sqlite3', '1.3.9' 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 |
为了准备将系统部署到生产环境中,我们运行带有特殊标志的bundle install,以防止本地安装任何生产gems(在这种情况下,它由pg和rails factor组成):
1 | $ bundle install --without production |
号
根据本教程,这是为了用pg和rails factor gems更新gemfile.lock。但是,这是gemfile.lock:

bundle是否应该将pg添加到gemfile.lock中?
该应用程序在云IDE上的Rails服务器上运行良好。以下是完整的日志,因为它有助于:

下面是Rails指出的错误:
1 | Specified 'postgresql' for database adapter, but the gem is not loaded. Add `gem 'pg'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord). (Gem::LoadError) |
当然,Heroku以默认运行PostgreSQL而闻名。
此错误有两种可能性:
Something is wrong with your Rails app (IE the PG gem is not loaded)Heroku doesn't have the db created or accessible

我在Heroku上遇到这个问题的唯一时间就是我没有创建或验证数据库。
我要做的是:
宝石把你的pg gem放在gem文件的一般部分。我知道这可能会导致你的开发环境出现问题;它将允许Heroku加载gem。您可以稍后再更改:
1 2 3 4 5 6 7 8 9 10 11 12 | #Gemfile source 'https://rubygems.org' gem 'pg' gem 'rails', '4.2.2' gem 'sass-rails', '5.0.2' 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 |

在Heroku中,确保已设置数据库,并已将其凭据添加到您的
。
辅导的
基本上,如果您已经设置了heroku pg数据库,请将凭证添加到您的
