1.首先执行：npm install jQuery --save-dev,在package.json里加入jQuery。
2.修改build下的webpack.base.conf.js
方法一：
首先加入：
const webpack = require("webpack")然后在module.exports 对象中加入：
?plugins: [ ???new webpack.optimize.CommonsChunkPlugin(‘common.js‘), ???new webpack.ProvidePlugin({ ?????jQuery: "jquery", ?????$: "jquery" ???}) ?]方法二：
先加入：
const webpack = require("webpack")然后：
?resolve: { ???extensions: [‘.js‘, ‘.vue‘, ‘.json‘], ???alias: { ?????‘vue$‘: ‘vue/dist/vue.esm.js‘, ?????‘@‘: resolve(‘src‘), ?????‘jquery‘: ‘jquery‘ ???} ?},最后：
?plugins: [ ???new webpack.ProvidePlugin({ ?????jQuery: "jquery", ?????$: "jquery" ???}) ?]3.在app.vue中调用jquery
?mounted: function() { ???console.log($); ???console.log($(‘#ss‘)[0].innerHTML); ?},打印结果:
