resources/js/app.js资源/js/app.js

require('./bootstrap');

window.Vue = require('vue');

resources/js/bootstrap.js资源/js/bootstrap.js

window._ = require('lodash');
try {
    window.Popper = require('popper.js').default;
    window.$ = window.jQuery = require('jquery');

    require('bootstrap');
} catch (e) {}

window.axios = require('axios');

window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
import Echo from 'laravel-echo';
window.xxx = 'xxx';
window.Pusher = require('pusher-js');

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: process.env.MIX_PUSHER_APP_KEY,
    cluster: process.env.MIX_PUSHER_APP_CLUSTER,
    encrypted: true
});

i ran我跑了

npm run dev

here is the result这是结果

in my view i have在我看来我有

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">

        <title>Laravel</title>
        <meta name="csrf-token" content="{{ csrf_token() }}">
        <script src="{{ asset('js/app.js') }}" defer></script>
        <link href="{{ asset('css/app.css') }}" rel="stylesheet">
    </head>
    <body>

    <script>
        console.log(Echo);
    </script>


    </body>
</html>

i keep getting我不断得到

Uncaught ReferenceError: Echo is not defined

i even added我什至加了

window.xxx = 'xxx';

in bootstrap.js to see if i can eccess xxx variable in my view but thats undefined as well (btw im not sure if thats how it works !! just trying some stuff )在 bootstrap.js 中查看我是否可以在我的视图中访问 xxx 变量，但这也是未定义的（顺便说一句，我不确定它是否是这样工作的！！只是尝试一些东西）

any idea?任何想法？

my folders structure is like我的文件夹结构就像

/pusher (root folder)
  +app
  +vendor
  +node_modules
  +resources/js
  -public
    index.php
    css/app.css
    js/app.js

Answer 1

Try removing defer from the <script.. portion.尝试从<script..部分中删除defer 。
