我正在使用Express 4.13.1,默认情况下它在端口3000上运行。
然而,当我将这一行添加到我的app.js:
时 /usr/local/bin/node --debug-brk=62380 --nolazy bin/www
Debugger listening on port 62380
Mon, 16 Nov 2015 13:59:13 GMT chatDel:server Listening on port 3000
该应用程序开始侦听端口3000和8080。 控制台输出是:
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');
var mongoose = require('mongoose');
var fs = require('fs');
var autoIncrement = require('mongoose-auto-increment');
var config = require('./config/serverConfig');
var routes = require('./routes/index');
var users = require('./routes/users');
var inmsg = require('./routes/inmsg');
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(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
app.use('/users', users);
app.use('/inmsg', inmsg);
app.listen(8080);
var connection = mongoose.createConnection(config.mongoose.connectionString);
global.db = connection;
autoIncrement.initialize(connection);
//load all files in model dir
fs.readdirSync(__dirname + '/models').forEach(function(filename){
if(~filename.indexOf('.js')) require(__dirname + '/models/' + filename);
});
// 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
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;
但要明确的是,两个端口的请求都有回应。
我错过了什么?
这是我的app.js
{
"name": "chatDel",
"version": "0.0.0",
"private": true,
"scripts": {
"start": "node ./bin/www"
},
"dependencies": {
"body-parser": "~1.13.2",

"mongoose-auto-increment": "^5.0.1",
"morgan": "~1.6.1",
"serve-favicon": "~2.3.0",
"stately.js": "^1.3.0"
}
}
这是我的Package.jason:
#!/usr/bin/env node
/**

*/
var app = require('../app');
var debug = require('debug')('chatDel:server');
var http = require('http');
/**

*/
var port = normalizePort(process.env.PORT || '3000');
app.set('port', port);
/**
* Create HTTP server.
*/
var server = http.createServer(app);
/**
* Listen on provided port, on all network interfaces.
*/
server.listen(port);
server.on('error', onError);
server.on('listening', onListening);
/**
* Normalize a port into a number, string, or false.
*/
function normalizePort(val) {
var port = parseInt(val, 10);
if (isNaN(port)) {
// named pipe
return val;
}
if (port >= 0) {
// port number
return port;
}
return false;
}
/**
* Event listener for HTTP server "error" event.
*/
function onError(error) {
if (error.syscall !== 'listen') {
throw error;
}
var bind = typeof port === 'string'
? 'Pipe ' + port
: 'Port ' + port;
// handle specific listen errors with friendly messages
switch (error.code) {
case 'EACCES':
console.error(bind + ' requires elevated privileges');
process.exit(1);
break;
case 'EADDRINUSE':
console.error(bind + ' is already in use');
process.exit(1);
break;
default:
throw error;
}
}
/**
* Event listener for HTTP server "listening" event.
*/
function onListening() {
var addr = server.address();
var bind = typeof addr === 'string'
? 'pipe ' + addr
: 'port ' + addr.port;
debug('Listening on ' + bind);
}
修改 我采取了更多行动:
当我更改侦听端口的行时:app.listen(3000)我在我的控制台中调试时出现以下错误:(同样,只有1个节点进程可见,然后在大约10秒后退出从错误。)
/ usr / local / bin / node --debug-brk = 49558 --nolazy bin / www 调试器侦听端口49558 端口3000已在使用中
使用退出代码1完成处理
编辑2: 这是我的www文件,它位于/ bin / www下它没有扩展名,虽然它是一个js文件,它是作为安装的一部分生成的。

答案 0 :(得分:1)
正如评论主题中所解释的那样 - 检查你的/ bin / www而不是app.js. :)
