1)安装gulp  参考:https://www.gulpjs.com.cn/

sudo npm install gulp-cli -g --unsafe-perm=true --allow-rootsudo npm install gulp -D --unsafe-perm=true --allow-rootsudo npx -p touch nodetouch gulpfile.js --unsafe-perm=true --allow-rootgulp --help

2)创建工程

安装 gulp 命令行工具npm install --global gulp-cli创建项目目录并进入npx mkdirp my-projectcd my-project在项目目录下创建 package.json 文件npm init安装 gulp，作为开发时依赖项npm install --save-dev gulp检查 gulp 版本gulp --version

3)实现逻辑功能

➜  my-project tree.|____readfile.js|____package-lock.json|____package.json|____gulpfile.js|____.idea当然了node_modules也是存在的

4)实现如下
|____readfile.js

let fs = require("fs");let path = require("path")async function asyncAwaitTask() {    let str = await fs.readFileSync(path.join(__dirname, "package.json")).toString();    let obj = JSON.parse(str);    console.log(obj.version);    return new Promise(function (resolve, reject) {        resolve("read file version done");    });}module.exports = {    asyncAwaitTask: asyncAwaitTask,};

|____package-lock.json
|____package.json

{  "name": "my-project",  "version": "1.0.0",  "description": "",  "main": "index.js",  "scripts": {    "test": "echo \"Error: no test specified\" && exit 1",    "deploy": "gulp"  },  "author": "",  "license": "ISC",  "devDependencies": {    "gulp": "^4.0.2"  }}

|____gulpfile.js

let readfile = require("./readfile");async function defaultTask(cb) {    let str = await readfile.asyncAwaitTask();    console.log(str)    cb();}exports.default = defaultTask;

5)运行

➜  my-project gulp[14:53:55] Using gulpfile ~/Desktop/my-project/gulpfile.js[14:53:55] Starting 'default'...1.0.0read file version done[14:53:55] Finished 'default' after 2.56 ms

或者用npm执行

➜  my-project npm run deploy> my-project@1.0.0 deploy /Users/jianan/Desktop/my-project> gulp[15:00:26] Using gulpfile ~/Desktop/my-project/gulpfile.js[15:00:26] Starting 'default'...1.0.0read file version done[15:00:26] Finished 'default' after 1.84 ms
