１.首先在package.json里加入，
<pre>"dependencies": {
"jquery": "^2.2.3"
},</pre>然后 npm install
2.在webpack.base.conf.js里加入
<pre>var webpack = require('webpack')</pre>3.在module.exports里最后加入
<pre>plugins: [
new webpack.optimize.CommonsChunkPlugin('common.js'),
new webpack.ProvidePlugin({
jQuery: "jquery",
$: "jquery"
})
]</pre>4.然后一定要重新 run dev
5.在main.js引入就ok了
<pre>import $ from 'jquery'</pre>
