'ApplicationRouteMix' 已定义但从未使用 [Ember.js]

Question

我正在创建一个身份验证来登录我的应用程序，但我遇到了这 3 个问题，我不知道如何继续，我是 ember 的新手，我不太了解如何修复问题，我正在学习它，在我遵循这个过程之后，我的应用程序不再出现，屏幕只变成空白，教程是 ember-simple-auth: http://ember-simple-auth.com/ - 谢谢进步：

控制台输出字面上拼出了问题：

/home/carlos/www/vendasapi-frontend/app/controllers/login.js 4:31 error 'session' is not defined no-undef

那里有 session: Ember.inject.service(session)。但是没有定义会话变量，所以你不能调用 Ember.inject.service ......你需要的只是：

session: Ember.inject.service('session') 甚至：

session: Ember.inject.service()

/home/carlos/www/vendasapi-frontend/app/routes/application.js 2:8 error 'ApplicationRouteMix' is defined but never used no- unused-vars 5:35 error 'ApplicationRouteMixin' is not defined no-undef

它说在第 2 行你导入为 ApplicationRouteMix 但你永远不会在任何地方使用它。然后在第 5 行，您正在使用 ApplicationRouteMixin 但尚未在任何地方定义它。那只是因为你打错了 - 你想要使用的是：

import ApplicationRouteMixin from 'ember-simple-auth/mixins/application-route-mixin';

'ApplicationRouteMix' 已定义但从未使用 [Ember.js]

'ApplicationRouteMix' is defined but never used [Ember.js]
