使用npm install -g 'xxx' 之后仍然报
Cannot find module 'xxx' 错误，可以通过设置环境变量来解决；
Java代码
export NODE_PATH=/usr/local/lib/node_modules/ echo $NODE_PATH
使用socket.io出现问题，按照demo使用<script src='http://localhost:2013/socket.io/socket.io.js'></script>出现错误：
"io is not defined"
将上述代码修改为：
<script src='socket.io/socket.io.js'></script>即可解决该问题。
如果将上述的src直接使用本机的socket.io的地址或者cdn的公开socket.io会出现
info - unhandled socket.io url.依旧不能使用
