Nowjs仍然没有使用快递3.0

Question

我试图让nowjs使用快递3.0，就像在this问题一样。我正在关注代码，但我仍然得到“现在没有定义”。

我在Oracle VM虚拟框中运行Ubuntu 12.04。

首先我创建一个快速应用程序。

$ express myBrilliantNewApp 

然后，我安装nowjs在新的目录中。

$ sudo npm install now 

添加服务器变量并立即使用它。

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

var everyone = require('now').initialize(server); 

然后，我应该能够做到这一点...

everyone.now.writesomething = function() { 
console.log('I would really like it if this shows up at the console') 
}; 

...和拨打电话，并检查什么大家是怎么一回事。

now.writesomething(); 
console.log(everyone); 

它不起作用。我得到：

[ReferenceError: now is not defined] 
ReferenceError: now is not defined 
at Object.<anonymous> (/home/jan/dev/apps/probeer1/app.js:44:1) 
at Module._compile (module.js:449:26) 
at Object.Module._extensions..js (module.js:467:10) 
at Module.load (module.js:356:32)

at Module.runMain (module.js:492:10) 
at process.startup.processNextTick.process._tickCallback (node.js:244:9) 

谁能告诉我我在做什么错在这里？

全面上市app.js

/** 
* Module dependencies. 
*/ 

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

var app = express(); 

app.configure(function(){ 
    app.set('port', process.env.PORT || 3000); 
    app.set('views', __dirname + '/views'); 
    app.set('view engine', 'jade'); 
    app.use(express.favicon()); 
    app.use(express.logger('dev')); 
    app.use(express.bodyParser()); 
    app.use(express.methodOverride()); 
    app.use(app.router); 
    app.use(express.static(path.join(__dirname, 'public'))); 
}); 

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

app.get('/', routes.index); 

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

var everyone = require('now').initialize(server); 


everyone.now.writesomething = function() { 
    console.log('I would really like it if this shows up at the console') 
}; 

now.writesomething(); 
console.log(everyone); 

Answer 1

在服务器上使用nowjs之前，你需要调用：

var nowjs = require('now'); 

要在客户机上使用nowjs你需要在你的HTML的脚本参考：

<script src="/nowjs/now.js"></script> 

Answer 2

看到这个答案的详细信息：Cannot find module 'now' - nowjs and nodejs

npm config set global true && \ 
    echo 'export NODE_PATH="'$(npm root -g)'"' >> ~/.bashrc && \ 
    . ~/.bashrc 

与全局标志

sudo npm install now -g
