手写一个自己vue-cli

1.安装vue-cli
npm install -g @vue/cli
https://cli.vuejs.org/zh/guide/cli-service.html

2.npm init -y 初始化包

cyp:
#!/usr/bin/env node console.log("hello cyp");

package.json

{
  "name": "vue-cli",
  "version": "1.0.0",
  "description": "",
  "bin": {
    "yd": "./bin/cyp"   //插入这行代码
  },
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

sudo npm link / npm link : 将包link到全局中去

4. npm install -g cyp :就能将这个包给别人用啦

cyp:

#!/usr/bin/env node

// console.log("hello cyp");

//核心处理命令行
const program = require("commander") //cnpm install commander  --save 安装包

program.version = ("0.0.1", "-v --version"); //cyp -v

cyp:

#!/usr/bin/env node

// console.log("hello cyp");

//核心处理命令行
const program = require("commander") //cnpm install commander  --save 安装commander包
// console.log("xxx")
program.version("0.0.1", "-v, --version"); //cyp -v

program.command("init", "初始化我们的项目");
program.parse(process.argv);

7.对文字进行渐变的包: npm install -save @darkobits/lolcatjs

//处理当用户进行版本号控制的时候
const Printer = require('@darkobits/lolcatjs');
// console.log("xxx")
program.version(Printer.default.fromString("hello world 加油，云苹"), "-v, --version"); //cyp -v

program.command("init", "初始化我们的项目");
program.parse(process.argv);
