大神，windows中编译后js报错

Uncaught TypeError: Cannot read property 'csrfToken' of undefined
     at Object.<anonymous> (app.3df1225….js:27701)
     at __webpack_require__ (app.3df1225….js:20)

目测是 resourses/assets/js/bootstrap.js 第31行 window.Laravel.csrfToken 未定义

github 上面相关作者给出的答案是在页面添加代码：

<script>
    window.Laravel = <?php echo json_encode([
        'csrfToken' => csrf_token(),
    ]); ?>
</script>

这目测很不科学，很不友好。大神有更好的解决方案吗？
