###安装 This is a complete Redis client for node.js. It supports all Redis commands, including many recently added commands like EVAL from experimental Redis server branches.
Install with:
npm install redis
Pieter Noordhuis has provided a binding to the official hiredis C library, which is non-blocking and fast. To use hiredis, do:
npm install hiredis redis
If hiredis is installed, node_redis will use it by default. Otherwise, a pure JavaScript parser will be used.
If you use hiredis, be sure to rebuild it whenever you upgrade your version of node. There are mysterious failures that can happen between node and native code modules after a node upgrade.

The performance of node_redis improves dramatically with pipelining, which happens automatically in most normal programs.
