注意需要在入口文件顶部指定#!/usr/bin/env node告诉系统使用node运行，否则报错

npm

package.json

• files: 可选配置项，指定发包时要包含的文件，如果不指定默认是*，https://docs.npmjs.com/cli/v8/configuring-npm/package-json#files
• bin: 简单来说就是配置可执行文件到系统Path,这样就可以直接用配置的名字执行该文件。

https://docs.npmjs.com/cli/v8/configuring-npm/package-json#bin

• main： 默认是index.js，指定当使用者require的时候的入口文件
