我想启动一个如下所示的JavaScript Express代理服务器:
var express = require("express"),
http = require("http"),
port = (process.env.PORT || 8001),
server = module.exports = express(),
httpProxy = require('http-proxy');
var proxy = httpProxy.createProxyServer();
// SERVER CONFIGURATION
// ====================
server.configure(function() {
server.use(function(req, res, next) {
if (req.url.indexOf('/bla') === 0) {
//console.log(res);
proxy.web(req, res, {target: 'http://bla.blabla.net'});
} else {
next();
}
});
server.use('/bla', express["static"](__dirname + "/../public"));
server.use(express.errorHandler({
dumpExceptions: true,
showStack: true
}));
server.use(express.bodyParser());
server.use(server.router);
});
// Start Node.js Server
http.createServer(server).listen(port);
它过去没有问题,但现在它失败了,虽然我没有更改代码。我收到此错误消息:
util.js中:634
ctor.prototype = Object.create(superCtor.prototype,{ ^
TypeError:无法读取属性'原型'未定义的
at Object.exports.inherits(util.js:634:43)

使用退出代码1完成处理
它可能与使用过的libs有关,因为我更新了它们并重新安装了jquery。我读过有关浏览器同步的错误,但实际上我并没有使用它。无论如何我安装了最新版本,但这并没有改变任何东西。有什么问题?

现在它正在运作。解决方案是删除http-proxy
库:
npm uninstall http-proxy
然后我将这些行添加到我的package.json
文件中:
"dependencies": {
"eventemitter3": "0.1.6",
"http-proxy": "~1.6"
}
npm install
一切正常后。
