in ./resources/assets/js/app.js

Module build failed: Error: Couldn't find preset "es2015" relative to directory "/home/insua/sites"

我是直接用

composer create-project laravel/laravel laravel --prefer-dist

安装的laravel最新版本,yarn安装npm依赖，然后npm run dev
没有修改laravel的任何文件，结果报错，找不到es2015这是咋回事呢

解决方案

npm install babel-preset-es2015 -g
