Javascript 导入和请求未正确加载到Web包中
我正在将Vue与Webpack一起使用,但当我导入或要求将另一个文件包含到我的主文档中时,该文件似乎已加载,因为它不会给我任何错误,但文件中的导入不会加载,并且我无法使用文件中的任何变量。例如,我有以下主要文档:Javascript 导入和请求未正确加载到Web包中,javascript,webpack,vuejs2,Javascript,Webpack,Vuejs2,我正在将Vue与Webpack一起使用,但当我导入或要求将另一个文件包含到我的主文档中时,该文件似乎已加载,因为它不会给我任何错误,但文件中的导入不会加载,并且我无法使用文件中的任何变量。例如,我有以下主要文档: import './bootstrap'; import VueRouter from 'vue-router'; Vue.use(VueRouter); let Default = Vue.component('Default', { te

var router = new VueRouter({
routes: [
{ path: '/', component: Default },

require('./sass/styles.scss');
new Vue({

我得到以下错误:uncaughtreferenceerror:Vue未定义
,就好像文件未包含一样。如果我对路径进行任何更改,我会得到一个“未找到文件”错误,因此我认为该文件位于。与文件中的任何变量相同,它们在主文件中不可用。这是我的webpack.config.js:
var path = require('path')
var webpack = require('webpack')
var inProduction = (process.env.NODE_ENV === 'production');
var ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
entry: './src/main.js',

非常感谢 您没有在引导文件中导出任何内容好的,我现在看到了,但是我应该导出什么?
