console.log(argv);

{ _: [ 123, 'ajanuw' ],
help: false,
version: false,
p: './',
'$0': 'AppData\\Roaming\\npm\\node_modules\\sh\\bin\\create-user-info.js' }
脚本文件 /bin/main.js
#!/usr/bin/env node
console.log(123);
package.json
{
"name": "sh",
"version": "1.0.0",
"description": "",
"main": "main.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"bin": {
"r32": "./bin/main.js"
}
}
在脚本根目录执行
npm i -g ./或则npm link测试完后删除npm unlink
r32 执行命令就会出现 123
这是一个返回 随机数的命令
