ember js 中的 Flash 消息无法正常工作。创建 Flash 对象时未定义对象

Flash messages in ember js not working. Object undefined when creating a flash object

组件。

{{#each flashMessages.queue as |flash|}}
  {{flash-message flash=flash messageStyle='bootstrap'}}
{{/each}}
<button {{action 'getFlash'}}> Click for Flash </button>

组件js

import Ember from 'ember';

export default Ember.Component.extend({
    flashMessages: Ember.inject.service(),
    actions:{
        getFlash(){
            alert(this.get('flashMessages'))
            const flashMessages = Ember.get(this, 'flashMessages');
            flashMessages.success('Success!');
        }
    }
});

错误消息:未捕获的类型错误:

所以服务注入由于某种原因没有工作。我错过了什么。 我参考的指南:https://github.com/poteto/ember-cli-flash#displaying-flash-messages

ember 安装 ember-bootstrap ember 安装 ember-cli-flash

安装了这两个。

每当我们安装任何 ember 插件时,都需要停止并启动 ember serve

一般来说,每当我遇到任何问题时,我都会在相应的项目 github 问题列表中搜索,这将帮助我解决。在这种情况下,我刚刚找到并确认了这个 issue and solution
