无法将 nib 包含到我的expressjs/nodejs 站点？

Question

我按照此处的示例将 nib 添加到我的网站：

/**
 * Module dependencies.
 */

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

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

// Configuration

app.configure(function(){
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(express.cookieParser());
  app.use(express.session({ secret: 'your secret here' }));
  app.use(require('stylus').middleware({ src: __dirname + '/public' }));
  app.use(nib());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

但是当我启动服务器时，出现此错误：

500 TypeError: Object #<IncomingMessage> has no method 'include'
at Object.handle (/home/alex/apps/foo/node_modules/nib/lib/nib.js:51:11)
at next (/home/alex/apps/foo/node_modules/express/node_modules/connect/lib/http.js:201:15)
at Object.handle (/home/alex/apps/foo/node_modules/stylus/lib/middleware.js:187:7)

at Array.0 (/home/alex/apps/foo/node_modules/express/node_modules/connect/lib/middleware/session/memory.js:52:9)

有什么建议来解决这个问题吗？

在“开发”模式下尝试此操作，因为您不想在生产环境中运行时编译手写笔：

app.configure('development', function(){
  var stylusMiddleware = stylus.middleware({
  src: __dirname + '/stylus/', // .styl files are located in `/stylus`
  dest: __dirname + '/public/', // .styl resources are compiled `/css/*.css`
  debug: true,
  compile: function(str, path) { // optional, but recommended
    return stylus(str)
      .set('filename', path)
      .set('warn', true)
      .set('compress', true)
      .use(nib());
    }
  });
  app.use(stylusMiddleware);  
  app.use(express.errorHandler({ dumpExceptions: true, showStack: true })); 
});

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

app.configure(function(){
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(app.router);
  app.use(express['static'](__dirname + '/public'));
});

这是我对笔尖和手写笔的常用设置。通过此设置，您需要将 require("stylus") 移至顶部，如 stylus = require("stylus")，类似于您的 <代码>require（“nib”）。

您必须在development之后列出常规configure方法列表。
