在非新鲜的 laravel 中安装带有身份验证的 laravel/ui

Question

我有未刷新的 Laravel 项目，将其升级到 6 和 7，现在我想通过这个文档安装 laravel ui auth。

https://laravel.com/docs/7.x/authentication

之后：

composer require laravel/ui

安装后：

php artisan ui vue --auth

然后：

npm install && npm run dev

这里我有错误：

 10% building 1/1 modules 0 active
webpack is watching the files…

 98% after emitting SizeLimitsPlugin

所以我需要解决方案，

我无法解决这个 sass 包错误。

Answer 1

卸载后重新安装解决

npm uninstall --save-dev sass-loader
npm install --save-dev sass-loader@7.1.0
