Heroku rake中止了？

Question

我在试着跑

heroku rake db:migrate

但是我一直收到这个错误

(in /app)

应用程序启动成功

但是我得到了这个错误

在我本地的开发中，看起来我使用的是Ruby1.8，但在heroku上，它看起来是1.9.1，这可能是引起了it....any关于如何修复这个问题的想法

这是我的gemfile，如果对您有帮助的话

source 'http://rubygems.org'

#gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
gem 'rails', '2.3.8'
gem 'will_paginate', '2.3.12'
gem 'googlecharts'
gem 'faker'
gem 'httparty'
gem 'bandsintown'
gem 'itunes-search-api','0.1.0', :path => 'vendor/gems/itunes-search-api-0.1.0'
gem 'i18n', '0.4.2'
gem "giggly", "~> 0.1.2"
gem "ruby-paypal",'0.0.5', :path => 'vendor/gems/ruby-paypal-0.0.5'


group :development, :test do
  gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
end

Answer 1

看起来你需要修改你的Gemfile，尝试使用下面的一个，看看它是否适用于你：

source 'http://rubygems.org'

gem 'rails', '2.3.8'
gem 'will_paginate', '2.3.12'
gem 'googlecharts'
gem 'faker'
gem 'httparty'
gem 'bandsintown'
gem 'itunes-search-api','0.1.0', :path => 'vendor/gems/itunes-search-api-0.1.0'
gem 'i18n', '0.4.2'
gem "giggly", "~> 0.1.2"
gem "ruby-paypal",'0.0.5', :path => 'vendor/gems/ruby-paypal-0.0.5'

group :production do
  gem 'test-unit'
  gem 'pg'
end


group :development, :test do
  gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
end
