vue-cli 引入jQuery，Bootstrap，popper的方法

1.安装插件

npm install jquery --save     //jquery插件
npm install bootstrap --save    //bootstrap
npm install --save popper.js   //popper.js

2.修改build目录下的webpack.base.conf.js配置文件：

1）加入webpack对象：var webpack=require('webpack');

2）在module.exports里面加入以下配置：　

plugins: [
  new webpack.optimize.CommonsChunkPlugin('common'),
  new webpack.ProvidePlugin({
   $: 'jquery',
   jQuery: 'jquery',
   Popper: ['popper.js', 'default']
  })
 ]

webpack.base.conf.js配置文件最终代码

'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
const webpack = require('webpack')

function resolve (dir) {
 return path.join(__dirname, '..', dir)
}

module.exports = {
 context: path.resolve(__dirname, '../'),
 entry: {
  app: './src/main.js'
 },
 output: {
  path: config.build.assetsRoot,
  filename: '[name].js',
  publicPath: process.env.NODE_ENV === 'production'
   ? config.build.assetsPublicPath
   : config.dev.assetsPublicPath
 },
 resolve: {
  extensions: ['.js', '.vue', '.json'],
  alias: {
   'vue$': 'vue/dist/vue.esm.js',
   '@': resolve('src'),
  }
 },
 module: {
  rules: [
   {
    test: /\.vue$/,
    loader: 'vue-loader',
    options: vueLoaderConfig
   },
   {
    test: /\.js$/,
    loader: 'babel-loader',
    include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client')]
   },
   {
    test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
    loader: 'url-loader',
    options: {
     limit: 10000,
     name: utils.assetsPath('img/[name].[hash:7].[ext]')
    }
   },
   {
    test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
    loader: 'url-loader',
    options: {
     limit: 10000,
     name: utils.assetsPath('media/[name].[hash:7].[ext]')
    }
   },
   {
    test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
    loader: 'url-loader',
    options: {
     limit: 10000,
     name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
    }
   }
  ]
 },
 node: {
  // prevent webpack from injecting useless setImmediate polyfill because Vue
  // source contains it (although only uses it if it's native).
  setImmediate: false,
  // prevent webpack from injecting mocks to Node native modules
  // that does not make sense for the client
  dgram: 'empty',
  fs: 'empty',
  net: 'empty',
  tls: 'empty',
  child_process: 'empty'
 },
 plugins: [
  new webpack.optimize.CommonsChunkPlugin('common'),
  new webpack.ProvidePlugin({
   $: 'jquery',
   jQuery: 'jquery',
   Popper: ['popper.js', 'default']
  })
 ]
}

3.在main.js中把jQuery，bootstrap的js和css通过import引进来

代码如下：

import $ from 'jquery'
import 'bootstrap/dist/css/bootstrap.min.css'
import 'bootstrap/dist/js/bootstrap.min'

最后重新启动一下：

npm run dev
