    <script type="text/javascript" src="http://libs.cdnjs.net/vue/2.0.0-alpha.8/vue.min.js"></script>

server.js

var express = require('express');
var app = express();
 

app.use(express.static(__dirname));
app.get('/', function (req, res) {
   res.sendFile( __dirname + "/" + "index.html" );
})

 
var server = app.listen(9527, function () {
 
  var host = server.address().address
  var port = server.address().port
 
  console.log("应用实例，访问地址为 http://%s:%s", host, port)
 
})

为什么页面中加载不到jquery和vue？
是express影响了scrpit src吗？为什么会这样？
