Question

我试图在laravel项目中使用moment.js，而不使用vue，但仍通过npm导入软件包。

我的app.js文件：

我的webpack.pix.js文件中的

看起来像这样：

require('moment/moment.js');
require('./bootstrap');
require('bootstrap-select');

然后在我的custom.js文件中，我得到了这个信息：

const mix = require('laravel-mix');    

mix.setResourceRoot('laravel/public');

mix.js('resources/js/app.js', 'public/js')
     .combine([
          'resources/theme/dist/js/app.js',
          'resources/theme/dist/js/app.init.js',
          'resources/theme/dist/js/sidebarmenu.js',
          'resources/theme/dist/js/waves.js',
          'resources/theme/assets/libs/perfect-scrollbar/dist/perfect-scrollbar.jquery.min.js',    
          'resources/theme/assets/extra-libs/sparkline/sparkline.js',  
          'resources/theme/dist/js/custom.js',
          'resources/js/custom.js'
     ], 'public/js/nice-admin.js')
     .copyDirectory('resources/theme/assets/images/', 'public/assets/images')
     .copyDirectory('resources/theme/dist/css/icons/material-design-iconic-font/fonts', 'public/fonts')
     .copy('node_modules/bootstrap-daterangepicker/daterangepicker.css', 'public/css/daterangepicker.css')
     .copy('node_modules/bootstrap-select/dist/css/bootstrap-select.min.css', 'public/css/bootstrap-select.min.css')
     .sass('resources/sass/app.scss', 'public/css', {
           implementation: require('node-sass')
}).options({processCssUrls: false})

我遇到以下错误：

$(function() {
    "use strict";

    let date = moment().format();
    console.log(date);
});

我已确认该时刻在我编译的app.js文件中。那么为什么我的custom.js文件看不到它，我该怎么做才能解决它？

目前，您没有为任何事物分配moment。根据{{3}}，您应将其分配给要使用的变量：

var moment = require（'moment'）;
moment（）。format（）;

但是，如果您想在app.js文件范围之外使用它，则将无法使用。一种方法是将其添加到window对象中：

window.moment = require('moment');

Moment js undefined Laravel
