我正在尝试一个基于node.js的示例项目，参考本教程：How To Write A Simple Node.js/MongoDB Web Service for an iOS App。我已经像这样配置了我的package.json：
{
"name": "mango-server",
"version": "0.0.1",
"private": true,
"dependencies": {
"express": "*",
"jade": "*"
}
}
问题是 - 当我尝试npm update或npm install时，它会在控制台上显示以下错误消息：
npm ERR! Error: No compatible version found: uglify-js@'^2.4.19'

我很无能，请建议。
