ruby-on-rails - LoadError：无法加载此类文件——部署到 Heroku 时的捆绑程序/设置

Question

将 rails 应用程序部署到 Heroku，它在本地运行良好。出现错误的步骤：

1. heroku create
2. 在 Heroku 中添加 Postgress 和 Redis 插件
3. git push heroku master
4. heroku run rake db:migrate

导致以下错误：

LoadError: cannot load such file -- bundler/setup

添加 buildpack: 后heroku/ruby，出现新错误
