使用gulp-babel时报错：Error: Cannot find module ‘@babel/core’

一、问题：

{ Error: Cannot find module '@babel/core'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:603:15)
    at Function.Module._load (internal/modules/cjs/loader.js:529:25)

二、解决：

npm i -D gulp-babel @babel/core @babel/preset-env
