想用nodejs实现一个简单的路由，安装运行出错?

server.js

const express=require('express');
const static=require('express-static');
const bodyParser=require('body-parser');
const multer=require('multer');
const multerObj=multer({dest: './static/upload'});
const mysql=require('mysql');
const cookieParser=require('cookie-parser');
const cookieSession=require('cookie-session');
const consolidate=require('consolidate');
const expressRoute=require('express-route');


var server = express()
server.listen(8080)

//获取前台请求数据
server.use(multerObj.any())
//cookie,session
  (function(){
    server.use(cookieParser());
    var keys=[]
    for(var i=0;i<100000;i++){
      keys[i]='a_'+Math.random()
    }

    server.use(cookieSession({
      name: 'sess_id',
      keys: keys,
      maxAge: 20*60*1000
    }))
  })()

//模板
server.engine('html', consolidate.ejs)
server.set('views', 'template')
server.set('view engine', 'html')


// route
var r1 = express.Router()
var r2 = express.Router()

server.use('/article', r1)
  r1.get('/1.html', function(req,res){
    res.send('我是文章').end()
  })
  r1.get('/2.html', function(req,res){
    res.send('我ye是文章').end()
  })

server.use('/blog', r2)
  r2.get('/a.html', function(req,res) {
    res.send('我是blog').end()
  })
  r2.get('/b.html', function(req,res) {
    res.send('我也是blog').end()
  })


// default: static
server.use(static('./static/'));

pack.json

{
  "devDependencies": {
    "body-parser": "^1.18.2",
    "consolidate": "^0.15.0",
    "cookie-parser": "^1.4.3",
    "cookie-session": "^2.0.0-beta.3",
    "express": "^4.16.2",
    "express-route": "^0.1.4",
    "express-static": "^1.2.5",
    "multer": "^1.3.0",
    "mysql": "^2.15.0",
    "static": "^2.0.0"
  }
}

const express=require('express');
const static=require('express-static');
const cookieParser=require('cookie-parser');
const cookieSession=require('cookie-session');
const bodyParser=require('body-parser');
const multer=require('multer');
const consolidate=require('consolidate');
const mysql=require('mysql');

//连接池
const db=mysql.createPool({host: 'localhost', user: 'root', password: '123456', database: 'blog'});

var server=express();
server.listen(8081);

//1.解析cookie
server.use(cookieParser('sdfasl43kjoifguokn4lkhoifo4k3'));

//2.使用session
var arr=[];
for(var i=0;i<100000;i++){
  arr.push('keys_'+Math.random());
}
server.use(cookieSession({name: 'zns_sess_id', keys: arr, maxAge: 20*3600*1000}));

//3.post数据
server.use(bodyParser.urlencoded({extended: false}));
//server.use(multer({dest: './www/upload'}).any());

//4.配置模板引擎
//输出什么东西
server.set('view engine', 'html');
//模板文件放在哪儿
server.set('views', './template/web');
//哪种模板引擎
server.engine('html', consolidate.ejs);

//接收用户请求

var r1= express.Router()
var r2= express.Router()


server.get('/', (req, res)=>{
  res.render('index.ejs');
});

server.use('/article/', r1)
  r1.get('/1.html', function(req, res){
    res.send('wobushi文章')
})

server.use('/blog/', r2)
  r2.get('/2.html', function(req, res){
    res.send('你是不是wen')
})

//4.static数据
server.use(static('./www'));
