我正在更新我的旧gulpfile.js,以前主要是将我的Sass编译成CSS,但是现在我试图让Gulp执行以下操作：

>同步浏览器,打开本地主机服务器 – 完成
>编译Sass => CSS – 完成
>使用JSHint – DONE显示任何JavaScript错误

>编译ES6 => ES6与Babel(WORKING ON)

>缩小所有资产(WORKING ON)

>显示项目文件大小 – 完成

>将index.html,style.css和图像部署到S3(WORKING ON)
>查看文件,当.scss或.html更改时,重新加载浏览器

问题

试图缩小我的Javascript并创建一个scripts.min.js
文件,它会为每个新的最小化的JavaScript添加后缀最小值
文件.

文件夹结构

index.html
gulpfile.js
package.json
.aws.json
.csscomb.json
.gitignore

assets
- css
style.css
style.scss

--partials
---base
---components
---modules

- img
- js
scripts.js

- dist
