Question

我正在使用网络服务而且我使用的是npm服务器和mongodb（我不知道这是否相关，但我想提供完整的背景）我像往常一样启动服务器并且突然npm服务器停止工作（我不知道它是否相关，但是当我运行一个脚本写入DB写入数据库然后粉碎时发生了这种情况）当我尝试再次启动它时会显示此错误消息：< / p>

LIB \ foo.js：

    module.exports = foo;

路由\ foo.js：

var express = require('express');
var router = express.Router();

var foo = require('../lib/foo.js');

/* GET home page. */
router.get('/getData', foo.getData);
router.post('/getData', foo.getData);

router.get('/register',foo.writeUser);
router.post('/register',foo.writeUser);

module.exports = router;

的package.json：

{
  "name": "foo",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www",
    "debug": "node-debug ./bin/www"

    "monk": "0.9.0",
    "morgan": "1.3.0",

app.js：

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');

//require routers
var foo = require('./routes/foo.js');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

// uncomment after placing your favicon in /public
//app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
//create public folder
app.use(express.static(path.join(__dirname, 'public')));

// app use routers
app.use('/foo',foo);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
    var err = new Error('Not Found');
    err.status = 404;
    next(err);
});

// error handlers
