@mapleshaw 好神奇，这是为什么。

由于很多第三方模块式基于linux下的，有些在win下会报错误，写node还是基于linux吧，win下当做学习下就够了，如果用第三方模块要看fork或者star数。

貌似是这样 我做这里的时候就没有把路由分离出去了...

命令已经旧了 现在用ejs搭建环境的命令是express -e ejs microblog -t会使用jade模版创建工程

不要用connect-mongodb,用connect-mongo. 用法是 var MongoStore = require('connect-mongo')(express);

错了 。 npm install jade --save

npm install jade -d

@newBingJ 我也碰到了这个问题，怎么解决？

@newBingJ 擦，就是没有启动数据库

请问怎么解决的？ 我卡了好久了

系统没有安装mongodb，使用brew install mongodb后，用终端执行代码mongod或者mongo，即可。

请问下在xp下的这个例子完成了，我遇到一大堆的错误，都做不下去了，express的版本问题真严重~~你要是完成了，能否发给我一份？不胜感激~

+1怒顶！

同问卡在这里两天了

@jianjianfengyun mongoStore = require('connect-mongodb')在后面加一个（express）就可以~~

怒顶 +1

这个问题我也纠结了好久。。哈哈仔细看了下 官方文档。。 我重新下来了 新的模块解决了。。。 mongoStore = require('connect-mongodb') 从来下载 connect-mongodb 多了一个 db 不知道 他俩有啥区别 。。现在不报错了。。

这个问题是怎么解决的。 求解 0 0

楼主，问下你的这个问题怎么解决的

怒顶

问下，我全局跟本地都安装了express,结果Quick Start的命名在cmd里面不能运行，提示说不是内部或外部命令，怎么办？？

dynamicHelpers lz有解决方法了吗？卡在此处。

使用时请注意版本问题，并且确认依赖的modules都已经下载配置好了

//继续使用app.use(app.router)，在app.js最后执行一下routes(app);即可

app.configure('development', function(){
  app.use(express.errorHandler());
});

routes(app);//这里执行

// routes/index.js 还按书上的来
module.exports=function(app){
  
  app.get('/',function(req,res){
    res.render('index',{
      title:'首页'
    });
  });
  
};

6F 请你你这个问题是怎么解决的了？我现在发现这个问题和你一样，能告诉一下我么？[email protected] 谢谢。

connect ETIMEDOUT 怀疑网络问题, 设置镜像吧 http://www.v2ex.com/t/15093

请问楼主，这个现在还没解决吗？app.use(express.router(routes));

我运行 npm install 更新包依赖的时候都出一大堆错误，晕死了，是因为我是xp系统么？

是不是这个例子在Windows XP下根本不可能运行的啊，出了一顿错误，郁闷啊

版本问题太多了，受不了了。

我已经暂时抛弃了书中的用法，继续进行下去， 但是使用dynamicHelper时又出错。

var MongoStore = require('connect-mongodb'); 加上了 app.use(express.session({ secret: settings.cookieSecret, store: new MongoStore({ db: settings.db }) }));

就会出错，如下：

TypeError: Cannot call method 'findOne' of null at MongoStore.MONGOSTORE.get (D:\express\microblog\node_modules\connect-mongodb\lib\connect-mongodb.js:115:15) at Object.session [as handle] (D:\express\microblog\node_modules\express\node_modules\connect\lib\middleware\session.js:298:11) at next (D:\express\microblog\node_modules\express\node_modules\connect\lib\proto.js:190:15) at Object.methodOverride [as handle] (D:\express\microblog\node_modules\express\node_modules\connect\lib\middleware\methodOverride.js:37:5) at next (D:\express\microblog\node_modules\express\node_modules\connect\lib\proto.js:190:15) at Object.cookieParser [as handle] (D:\express\microblog\node_modules\express\node_modules\connect\lib\middleware\cookieParser.js:60:5) at next (D:\express\microblog\node_modules\express\node_modules\connect\lib\proto.js:190:15) at multipart (D:\express\microblog\node_modules\express\node_modules\connect\lib\middleware\multipart.js:62:61) at module.exports (D:\express\microblog\node_modules\express\node_modules\connect\lib\middleware\bodyParser.js:57:9) at urlencoded (D:\express\microblog\node_modules\express\node_modules\connect\lib\middleware\urlencoded.js:52:72)

怎么连接mongodb

app.use(express.router(routes)); //app.use(app.router);

我也是這裡卡了。。。難道是express 3版本以上沒有這個router方法了?

后面还有无数的版本问题等着你呢！！！莫着急

@saighost 好的，谢谢，确实js学得不够，甚至连怎么找错误都不懂。

@saighost app.use(app.router);可以用，但是照书里写的做用了app.use(express.router(routes)); 结果报express找不到router方法了，请问这个你知道原因么？被卡住了。。。

我觉得错误还是很好看的呀，， 500 Error: Cannot find module 'jade' 明显提示是没有jade模版

/**

• Module dependencies. */

var express = require('express') , routes = require('./routes') , http = require('http') , path = require('path');

var app = express(); //var app = module.exports = express.createServer();

http.createServer(app).listen(app.get('port'), function(){ console.log("Express server listening on port " + app.get('port')); });

最新的错误， 貌似没有router这个方法。

[root@localhost microblog]# node app.js

/home/xxx/Project/nodeJs/microblog/app.js:32 app.use(express.router(routes)); ^ TypeError: Object function createApplication() { var app = connect(); utils.merge(app, proto); app.request = { proto: req }; app.response = { proto: res }; app.init(); return app; } has no method 'router' at Function. (/home/xxx/Project/nodeJs/microblog/app.js:32:19)

问题解决了， 我从mongodb官网下载了程序，启动数据库。

上面的问题初步解决，又有新的问题： 我已经安装了 mongoDB connect-mongo

ok 主页的问题解决了。多谢WillWen

你的例子是ejs，却用了jade

app.set('view engine', 'ejs');


npm install ejs

刚才 npm install jade之后 运行app.js成功，但主页是express提供的原始的。

npm install jade

Express server listening on port 3000
