Question

我是node.js的新手。我正在尝试使用快速模块的脚本。我已经安装了express，using，

npn install express

当我运行代码时出现错误

TypeError: Cannot read property 'handle' of undefined
at Function.app.use (c:\node_modules\express\lib\application.js:113:9)
at Object.<anonymous> (c:\node\uploadResize.js:13:6)
at Module._compile (module.js:456:26)
at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)
at node.js:901:3

如何解决这个问题？

这是我的节点脚本。

var http    = require('http'),  // Libraries
util    = require('util'),
fs      = require('fs'),
couch   = require('cradle'),
connect = require('express'),
endsWith,   // Internal Functions
determineMimeType,
upload;

connect()
.use(connect.bodyParser())
.use(upload)
.listen(3000);

upload = function (req, res, next) {
    // function body
}

Answer 1

您需要在传递给upload之前为app.use分配值

Answer 2

使用类似的东西：

var app = express();

app.configure(function() {
  var hourMs = 1000*60*60;
  app.use(express.static('c:\\node', { maxAge: hourMs }));
  app.use(express.directory('c:\\node'));
  app.use(express.errorHandler());
});

Answer 3

代码不是npm install express ??

那么dir node_modules在同一个目录中，你有你的应用程序

C：\节点\ node_modules C：\节点\ app.js

node.js + express error：无法读取未定义的属性'handle'
