我不知道什麼是錯我的代碼推杆未定義! Laravel 5.4 Laravel回聲

這裏是我的app.js

/** 
* First we will load all of this project's JavaScript dependencies which 
* include Vue and Vue Resource. This gives a great starting point for 
* building robust, powerful web applications using Vue and Laravel. 
*/ 

require('./bootstrap'); 

/** 
* Next, we will create a fresh Vue application instance and attach it to 
* the page. Then, you may begin adding components to this application 
* or customize the JavaScript scaffolding to fit your unique needs. 
*/ 

Vue.component('chat-message', require('./components/ChatMessage.vue')); 
Vue.component('chat-log', require('./components/ChatLog.vue')); 
Vue.component('chat-composer', require('./components/ChatComposer.vue')); 

let idIsExist = document.getElementById('chat-init'); 

if(idIsExist !== null) { 
    const app = new Vue({ 
     el: '#chat-init', 
     http: { 
      emulateJSON: true, 
      emulateHTTP: true 
     }, 
     data: { 
      messages: [] 
     }, 
     methods: { 
      addMessage(message) { 
       axios.post('page-send-message', message).then(response => { 
        if(response.status !== 200) { 
         message = { 
          messages: response.statusText, 
          user: { 
           name: response.status 
          } 
         } 
        } 
        return this.messages.push(message); 
       }); 
      } 
     }, 
     created() { 
      axios.get('page-messages').then(response => { 
       this.messages = response.data; 
      }); 

      Echo.join('page-chat').here().joining().leaving().listen('MessagePosted', e => { 
       console.log(e); 
      }); 
     } 
    }); 
} 

Here's my `bootstrap.js` 

window._ = require('lodash'); 

/** 
* We'll load jQuery and the Bootstrap jQuery plugin which provides support 
* for JavaScript based Bootstrap features such as modals and tabs. This 
* code may be modified to fit the specific needs of your application. 
*/ 

window.$ = window.jQuery = require('jquery'); 
require('bootstrap-sass'); 

/** 
* Vue is a modern JavaScript library for building interactive web interfaces 
* using reactive data binding and reusable components. Vue's API is clean 
* and simple, leaving you to focus on building your next great project. 
*/ 

window.Vue = require('vue'); 
require('vue-resource'); 

/** 
* We'll register a HTTP interceptor to attach the "CSRF" header to each of 
* the outgoing requests issued by this application. The CSRF middleware 
* included with Laravel will automatically verify the header's value. 
*/ 

// Laravel Global Variable to use Laravel.csrfToken 
let csrfToken = document.querySelector('meta[name="csrf-token"]').getAttribute('content'); 

Vue.http.interceptors.push((request, next) => { 
    request.headers.set('X-CSRF-TOKEN', csrfToken); 
    next(); 
}); 

/** 
* We'll load the axios HTTP library which allows us to easily issue requests 
* to our Laravel back-end. This library automatically handles sending the 
* CSRF token as a header based on the value of the "XSRF" token cookie. 
*/ 

window.axios = require('axios'); 

window.axios.defaults.headers.common = { 
    'X-CSRF-TOKEN': csrfToken, 
    'X-Requested-With': 'XMLHttpRequest' 
}; 

這裏是我的bootstrap.js

/** 
* Echo exposes an expressive API for subscribing to channels and listening 
* for events that are broadcast by Laravel. Echo and event broadcasting 
* allows your team to easily build robust real-time web applications. 
*/ 

import Echo from "laravel-echo" 

window.Echo = new Echo({ 
    broadcaster: 'pusher', 
    key: '3c45e6945c69f616f4a3' 
}); 

這裏是我的事件MessagePosted.php

<?php 

namespace App\Events; 

use App\User; 
use App\Message; 
use Illuminate\Broadcasting\Channel; 
use Illuminate\Queue\SerializesModels; 
use Illuminate\Broadcasting\PrivateChannel; 
use Illuminate\Broadcasting\PresenceChannel; 
use Illuminate\Foundation\Events\Dispatchable; 
use Illuminate\Broadcasting\InteractsWithSockets; 
use Illuminate\Contracts\Broadcasting\ShouldBroadcast; 

class MessagePosted implements ShouldBroadcast 
{ 
    use Dispatchable, InteractsWithSockets, SerializesModels; 

    /** 
    * 
    * @var Message 
    * 
    */ 

    public $message; 

    /** 
    * 
    * @var User 
    * 
    */ 

    public $user; 

    /** 
    * Create a new event instance. 
    * 
    * @return void 
    */ 
    public function __construct(Message $message, User $user) 
    { 
     $this->message = $message; 
     $this->user = $user; 
    } 

    /** 
    * Get the channels the event should broadcast on. 
    * 
    * @return Channel|array 
    */ 
    public function broadcastOn() 
    { 
     return new PresenceChannel('page-chat'); 
    } 
} 

之後建立我在控制檯

Uncaught ReferenceError: Pusher is not defined 
    at PusherConnector.connect (eval at <anonymous> (app.js:345), <anonymous>:546:31) 
    at PusherConnector.Connector (eval at <anonymous> (app.js:345), <anonymous>:192:14) 
    at new PusherConnector (eval at <anonymous> (app.js:345), <anonymous>:537:135) 
    at new Echo (eval at <anonymous> (app.js:345), <anonymous>:689:30) 
    at eval (eval at <anonymous> (app.js:145), <anonymous>:59:15) 
    at Object.<anonymous> (app.js:145) 
    at __webpack_require__ (app.js:20) 
    at eval (eval at <anonymous> (app.js:418), <anonymous>:8:1) 
    at Object.<anonymous> (app.js:418) 
    at __webpack_require__ (app.js:20) 

得到這個錯誤我已經安裝Independencies

composer require pusher/pusher-php-server 
npm install --save laravel-echo pusher-js 

你能幫如何解決我的問題。問題是Pusher沒有定義,我不知道爲什麼。
