这是我的代码

/************************/

import Ember from "ember";

var TodosController = Ember.ArrayController.extend({

actions: {

createTodo: function(){

  // Get the todo title by the "New Todo" input 
  var title = this.get('newTitle');
  if(!title.trim()){ return; }

  // Create the new Todo model
  var todo = this.store.createRecord('todo', {
    title: title,
    isCompleted: false
  });

  // Clear the 'New Todo' input field
  this.set('newTitle', '');

  // Save the new model
  todo.save();
},

clearCompleted: function(){
  var completed = this.filterBy('isCompleted', true);
  completed.invoke('deleteRecord');
  completed.invoke('save');
}
},

remaining: function() {
return this.filterBy('isCompleted', false).get('length'); …

当我使用此命令“npm install -g ember-cli”安装 ember-cli 时，在终端中显示此错误。
