启动Rails服务器时出错：767：''（JSON :: ParserError）处出现意外令牌

Question

我的代码中的某个地方现在存在错误，我无法正确启动服务器。请帮助

不建议使用警告：不建议使用单个arity模板处理程序。模板处理程序必须现在接受两个参数，视图对象和视图对象的源。更改：

Coffee :: Rails :: TemplateHandler.call（template）至：Coffee :: Rails :: TemplateHandler.call（模板，源）（从C：/Users/User/Desktop/RubyTutorials/testdev/config/application.rb：9调用）=>引导彪马=> Rails 6.0.0应用程序正在开发中=>运行rails server --help获得更多启动选项退出中追溯（最近一次通话）：46：来自垃圾箱/轨道：4：在
