node.js - app.use(bodyParser.json()); and bodyParser.urlencoded({ extended: true }) method unresolved -

i using webstorm , have installed body-parser module bodyparser.json , bodyparser.urlencoded still gives unresolved method error.

var express = require('express'); var connect = require('connect'); var logger  = require('morgan'); var bodyparser = require('body-parser'); var app = express(); port = process.env.port || 8080;  app.use(logger('dev')); app.use(bodyparser.urlencoded({ extended: true })); app.use(bodyparser.json());  require('./routes.js')(app);  app.listen(port);  console.log('the app runs on port ' + port); 

routes

   var requests = require('config/requests');  var request = require('request');    module.exports = function(app) {    app.get('/', function(req, res) {      res.end("node-android-chat-project");  });   app.post('/login',function(req,res){     var name = req.body.name;         var mobno = req.body.mobno;         var reg_id = req.body.reg_id;      requests.login(name,mobno,reg_id,function (found) {         console.log(found);         res.json(found); });      });  app.post('/send',function(req,res){     var fromu = req.body.from;     var fromn = req.body.fromn;         var = req.body.to;         var msg = req.body.msg;       requests.send(fromn,fromu,to,msg,function (found) {         console.log(found);         res.json(found); });      });  app.post('/getuser',function(req,res){     var mobno = req.body.mobno;      requests.getuser(mobno,function (found) {         console.log(found);         res.json(found); });      });  app.post('/logout',function(req,res){     var mobno = req.body.mobno;       requests.removeuser(mobno,function (found) {         console.log(found);         res.json(found); });      }); 

};

trying installing body-parser module again.

use npm install body-parser --save
