node服务端保存文件报错

路由文件

var express = require('express');
var router = express.Router();
var connect_multiparty = require('connect-multiparty');
var multiparty = connect_multiparty();

/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('index', { title: 'Express' });
});

router.post("/",multiparty,function(req, res){
   var target_path = __dirname + '\\upload\\jj.jpg' ;
  // var target_path = __dirname + '/upload/jj.jpg' ;
  console.log(" req.files.file.path=",req.files.file.path);
  console.log("target_path===",target_path);
   fs.renameSync(req.files.file.path, target_path, function (err) {
      if (err) {
            console.log("出错了===",err);
      }
          console.log(" target_path=",target_path);
          console.log(" req.files.file.path=",req.files.file.path);
          console.log(" 成功");
   });
})

module.exports = router;

req.files.file.path 有值 C:\Users\INFACE~1\AppData\Local\Temp\830hVyqCRNoHoPfcbdKtAs3L
target_path 的值为 F:\upload\myapp\routes\upload\jj.jpg。
执行 fs.renameSync 方法就报错

你没有引入fs模块
