Express框架给出了一个非常奇怪的错误 [英] Express framework giving a very strange error

问题描述

我正在尝试在节点中使用Express，安装所有好的，编译，得到了npm并安装了express：

I'm trying to use Express in node, install everything okay, compiled, got npm and installed express with:

npm安装表达

npm install express

问题是，每次我尝试需要它，它给我一个错误！
看看，一个简单的文件app.js为：

The problem is, everytime I try to "require" it, it gives me an error! Take a look, a simple file app.js as:

var express = require('express');

当我运行它：

tlab065:~/proj/Express-server-abstraction> node app.js 
node.js:116
        throw e; // process.nextTick error, or 'error' event on first tick
        ^
TypeError: Cannot read property 'prototype' of undefined
    at Object.<anonymous> (/people/home/jdomingues/local/node/lib/node/.npm/express/1.0.7/package/lib/express/server.js:87:44)    
    at Module._compile (module.js:373:26)
    at Object..js (module.js:379:10)
    at Module.load (module.js:305:31)
    at Function._load (module.js:271:10)
    at require (module.js:317:19)
    at Object.<anonymous> (/people/home/jdomingues/local/node/lib/node/.npm/express/1.0.7/package/lib/express/index.js:28:31)
    at Module._compile (module.js:373:26)
    at Object..js (module.js:379:10)
    at Module.load (module.js:305:31

有人可以帮我吗？为什么我得到这个错误？我可以如何安装不同版本的快递？

Can someone help me? Why am I getting this error? How can I maybe install a different version from express?

推荐答案

问题是你可能有最新的连接（而不是你需要安装最新的连接）命令@Shripad显示是有帮助的，将可能会显示你已连接1.0， yay ...呃哦，表达还没有准备好1.0连接，这样做回到0.5.10：

The issue is that you probably have the latest connect (as opposed to "you need to install the latest connect") the command @Shripad showed is helpful and will probably show you that you have connect 1.0, yay...uh oh express isn't quite ready for 1.0 connect, do this to go back to 0.5.10:

npm install connect@0.5.10
