我运行npm install -g cradle并获得输出：
npm http GET https://registry.npmjs.org/cradle
.... lots of more GET's .....
cradle@0.6.3 C:\Users\...\npm\node_modules\cradle
├── vargs@0.1.0
├── request@2.9.153
└── follow@0.7.1
一切似乎都很好。
但是当我运行我的server.js
var fs = require("fs");
var express = require("express");
var site = express.createServer();
var io = require("socket.io").listen(site);
var cradle = require('cradle');
io.set('log level', 1);
// Determine which dist directory to use
var dir = process.argv.length > 2 && "./dist/" + process.argv[2];
// Use custom JS folder based off debug or release
dir && site.use("/assets/js", express.static(dir + "/js"));
dir && site.use("/assets/css", express.static(dir + "/css"));
// Serve static files
site.use("/app", express.static("./app"));
site.use("/assets", express.static("./assets"));
site.use("/dist", express.static("./dist"));
// Serve favicon.ico
site.use(express.favicon("./favicon.ico"));
// Ensure all routes go home, client side app..
site.get("*", function (req, res) {
fs.createReadStream("./index.html").pipe(res);
});
// Communication with clients
io.sockets.on('connection', function (socket) {
console.log('user connected');
socket.on('testCommunication', function (message, fn) {
fn(message + ' world');
});
});
site.listen(8000);
，我得到输出：
info - socket.io started
node.js:201
throw e; // process.nextTick error, or 'error' event on first tick
^

该模块与 socket.io、express 等位于同一目录中，我可以毫无问题地加载。我已经盯着这个错误一个小时了。我以前在mac上使用过cradle，它就像一个魅力，现在我在windows上，这可能与它有关吗？否则我一无所知。有任何想法吗？
