第一个nodejs应用程序,它是说更新您的中间件使用量较少

Question

我刚才用homebrew安装了nodejs.

然后我创建了一个文件夹,并安装了express:

npm install -g express

然后,我创建了一个新项目:

express -H --css less --sessions foo

现在,当我尝试运行应用程序时:

node app.js

我明白了:

/Users/blah/dev/testing/nodetest1/foo/node_modules/less-middleware/lib/middleware.js:50
    throw new Error('Please update your less-middleware usage: http://goo.gl/Y
          ^
Error: Please update your less-middleware usage: http://goo.gl/YnK8p0
    at module.exports.less.middleware (/Users/blah/dev/testing/nodetest1/foo/node_modules/less-middleware/lib/middleware.js:50:11)
    at Object.<anonymous> (/Users/snad/dev/testing/nodetest1/foo/app.js:26:35)
    at Module._compile (module.js:456:26)

    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:902:3

我的app.js看起来像:

/**
 * Module dependencies.
 */

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

var app = express();

// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'hjs');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(express.cookieParser('your secret here'));
app.use(express.session());
app.use(app.router);
app.use(require('less-middleware')({ src: path.join(__dirname, 'public') }));
app.use(express.static(path.join(__dirname, 'public')));

// development only
if ('development' == app.get('env')) {
  app.use(express.errorHandler());
}

app.get('/', routes.index);
app.get('/users', user.list);

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

Answer 1

我更改了以下行:

app.use(require('less-middleware')({ src: path.join(__dirname, 'public') }));

至:

app.use(require('less-middleware')(path.join(__dirname, 'public')));

它现在有效.奇怪的是,这是一个全新的nodejs和express安装应用程序.
