如何解决这个问题？

嗯，有一件事，没有db适配器被传递给Heroku。确保您的heroku应用程序有一个数据库，一个

您的应用程序需要一个数据库连接，但您没有指定适当的适配器。如果您正在使用Heroku Postgres，则需要添加类似于

gem'pg'，：group=>：production

的内容，并确保在Heroku配置中有

数据库\u URL

您需要在Gemfile中的生产环境中添加pg gem

  group :production
    gem 'pg'
  end

然后跑

  heroku rake db:migrate   #create db tables for production

 git push heroku master    #pushed the latest changes to production

 heroku restart        # it will start the server again with new changes

---

它现在应该可以工作了。

您的heroku日志如何为windows提供路径？C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/specifications/ZenTest-4.8.4.gemspec可能是您将gems与代码一起推送的吗？

  heroku rake db:migrate   #create db tables for production

 git push heroku master    #pushed the latest changes to production

 heroku restart        # it will start the server again with new changes
