麻烦推到heroku使用rails应用程序

Question

帮助将不胜感激。出于某种原因，即使我的本地版本工作正常，我推送到heroku也不起作用。

我正在部署一个rails应用程序。

git push heroku后，和heroku运行rake db：migrate我在我的网站上得到一个应用程序错误。

编辑我把整个背部走线

我注意到有废弃警告，但IM之后的迈克尔·哈特尔本书适合初学者学习轨道，他说忽略它们。

我做

heroku stack 

，我雪松堆栈以及

的environment.rb文件内，内容是...

1. # Load the rails application 
2. require File.expand_path('../application', __FILE__) 
3. 
4. # Initialize the rails application 
5. SampleApp::Application.initialize!

添加此宝石的Gemfile gem'bcrypt-ruby'，'〜> 3.0.0' 可能你的宝石在你当地的宝石上使用它。 不要忘记git add。
