所以我删除了braintree gem并在我的网络应用上添加了条纹gem，方法是删除gem 'braintree'并将gem 'stripe'添加到我的Gemfile中。
我忘记在bundle install之前运行git push。
推动失败了，说

当我查看我推送的内容时，它显示我只更改了Gemfile，而不是Gemfile.lock
我当时并没有真正想到，所以我运行了heroku运行捆绑安装但它仍然没有工作......然后我意识到我需要在我的开发服务器上运行bundle install，git add ，提交和推动。我做到了，部署成功了。
我应该做的，然后检查Heroku以查看应用程序是否有效，但我继续我的开发环境。 3周后，我现在陷入困境，无法使我的生产服务器正常工作，因此无法帮助它。之所以如此，是因为如果我在更改宝石之前恢复部署，Heroku应用程序就可以工作。如果我在更换宝石后恢复到第一次成功的Heroku部署，它就无法工作。
最重要的是，它正在开发中，但Heroku只给我状态= 500只用于HomeController中的任何东西。我的ProductController和SessionsController在Heroku中运行得很好。有人请帮帮我。
