gulp打包工具

话不多说，适配了半天终于找到几个能用的插件了。

这是pack.json文件。目前能兼容es6

{
  "name": "gulp-test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-core": "^6.26.3",
    "babel-preset-env": "^1.7.0",
    "babel-preset-es2015": "^6.24.1",
    "gulp": "^4.0.2",
    "gulp-babel": "^7.0.1",
    "gulp-clean-css": "^4.2.0",
    "gulp-htmlmin": "^5.0.1",
    "gulp-imagemin": "^5.0.3",
    "gulp-uglify": "^3.0.2"
  }
}

目前用的gulp4，task里面要加done()，执行方法里加同步（异步）操作
