在执行如下脚手架命令时出现错误。

$ rails g scaffold team name:string city:string championships:integer

Answer 1

我遇到了和你一样的问题。我修复了这个问题，安装。

gem 'active_model_serializers', '~> 0.10.0.rc1' 。

之前，我有0.9.4版本的这个宝石。现在脚手架生成器工作正常。

谢谢

有同样的问题&发现如果你安装了活动管理员，也会发生这种情况。

解决办法是在您的 config/application.rb:

config.app_generators.scaffold_controller = :scaffold_controller
