Express server listening on port 3000

Error: Cannot find module ‘jade’ at Function.Module._resolveFilename (module.js:338:15) at Function.Module._load (module.js:280:25) at Module.require (module.js:362:17) at require (module.js:378:17) at new View (/home/xxx/Project/nodeJs/microblog/node_modules/express/lib/view.js:42:49) at Function.app.render (/home/xxx/Project/nodeJs/microblog/node_modules/express/lib/application.js:486:12) at ServerResponse.res.render (/home/xxx/Project/nodeJs/microblog/node_modules/express/lib/response.js:676:7) at exports.index (/home/xxx/Project/nodeJs/microblog/routes/index.js:7:7) at callbacks (/home/xxx/Project/nodeJs/microblog/node_modules/express/lib/router/index.js:165:11) at param (/home/xxx/Project/nodeJs/microblog/node_modules/express/lib/router/index.js:139:11) GET / 500 93ms

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

ok 主页的问题解决了。多谢WillWen

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

[root@localhost microblog]# node app.js Express server listening on port 3000

/home/xxx/Project/nodeJs/microblog/node_modules/connect-mongo/lib/connect-mongo.js:126 throw new Error(‘Error connecting to database’); ^ Error: Error connecting to database at module.exports.MongoStore.proto (/home/xxx/Project/nodeJs/microblog/node_modules/connect-mongo/lib/connect-mongo.js:126:15) at Db.open (/home/xxx/Project/nodeJs/microblog/node_modules/connect-mongo/node_modules/mongodb/lib/mongodb/db.js:253:16) at Server.connect.connectionPool.on.server._serverState (/home/xxx/Project/nodeJs/microblog/node_modules/connect-mongo/node_modules/mongodb/lib/mongodb/connection/server.js:408:7) at EventEmitter.emit (events.js:115:20) at connection.on.connectionStatus (/home/xxx/Project/nodeJs/microblog/node_modules/connect-mongo/node_modules/mongodb/lib/mongodb/connection/connection_pool.js:93:15) at EventEmitter.emit (events.js:91:17) at Socket.errorHandler (/home/xxx/Project/nodeJs/microblog/node_modules/connect-mongo/node_modules/mongodb/lib/mongodb/connection/connection.js:382:10) at Socket.EventEmitter.emit (events.js:88:17) at Socket._destroy.self.errorEmitted (net.js:335:14)

问题解决了， 我从mongodb官网下载了程序，启动数据库。

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.<anonymous> (/home/xxx/Project/nodeJs/microblog/app.js:32:19)

/**

• Module dependencies. */

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

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

var MongoStore = require(‘connect-mongo’)(express); var settings = require(‘./settings’);

//var app = module.exports = express.createServer(); app.configure(function(){ app.set('port’, process.env.PORT || 3000); app.set('views’, __dirname + ‘/views’); app.set('view engine’, ‘ejs’); app.use(express.favicon()); app.use(express.logger(‘dev’)); app.use(express.bodyParser()); app.use(express.methodOverride()); app.use(express.cookieParser()); app.use(express.session({ secret: settings.cookieSecret, store: new MongoStore({ db: settings.db }) })); app.use(express.router(routes)); //app.use(app.router); app.use(express.static(__dirname + ‘/public’)); });

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

app.get('/’, routes.index); app.get('/u/:user’, routes.user); app.post('/post’, routes.post); app.get('/reg’, routes.reg); app.post('/reg’, routes.doReg); app.get('/login’, routes.login); app.post('/login’, routes.doLogin); app.get('/logout’, routes.logout);

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

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。
