SassError：未定义的函数 Laravel Vue

问：

我正在尝试安装项目的所有依赖项。Laravel Vue

从指令中，它说我需要运行 . 现在，当我运行它时，我正在收到npm run dev

> ERROR in ./resources/js/src/@core/scss/vue/libs/toastification.scss

我已经搜索了解决这个问题，有些人建议在文件中有一些依赖项，我需要提供指向它的链接。但是当我检查我的 sass 包时，我发现这个 -package-lock.jsonsassresolved

"sass": {
    "version": "1.32.13",
    "resolved": "https://registry.npmjs.org/sass/-/sass-1.32.13.tgz",
    "integrity": "sha512-dEgI9nShraqP7cXQH+lEXVf73WOPCse0QlFzSD8k+1TcOxCMwVXfQlr0jtoluZysQOyJGnfr21dLvYKDJq8HkA==",
    "dev": true,
    "requires": {
        "chokidar": ">=3.0.0 <4.0.0"
    },

现在我不知道去哪里看，怎么解决这个问题！ 有什么想法吗???
