安装iodocs我this problem开始，所以我试图在Linux上
npm install --force
看来工作，只有一个警告：
npm WARN [email protected] package.json: bugs['web'] should probably be bugs['url']
但是当我尝试运行它，它给了我：
[[email protected] iodocs]$ node ./app.js
The "sys" module is now called "util". It should have a similar interface.
node.js:201
throw e; // process.nextTick error, or 'error' event on first tick
^
Error: Cannot find module 'hashlib'

我不知道该如何处理它，请给我一些启示。
顺便说一句，我试图在Linux 2.6.35.14-97.44.amzn1.x86_64 EC2实例上安装iodocs。
