解决方案：
官方公告！！！
https://github.com/element-plus/element-plus/issues/15834

将 sass版本变更为 1.79.0

npm i sass@1.79.3

之后发现，比之前好点了，但是还是会有警告，不过没有报错了。

解决！不警告和报错了！

总结：

警告和报错的原因：

这些警告是由于 Dart Sass 版本升级后出现的弃用警告，主要有两个方面的问题：

全局内置 mix 函数弃用： Dart Sass 建议用 color.mix 替代 mix 函数，以避免弃用问题。Element Plus 的主题文件 var.scss 中使用了 mix，在未来的 Dart Sass 3.0.0 中可能会不兼容。

全局变量声明的弃用： Sass 即将不再允许使用 !global 在局部作用域中声明新变量。解决方法是声明变量 $B 在全局作用域中初始化（例如 $B: null;），然后在局部作用域中更新它。

Deprecation Warning: Global built-in functions are deprecated and will be removed in Dart Sass 3.0.0.

旧版Sass API的警告：

提示正在使用旧的JS API，建议升级到最新版本的Dart Sass以兼容新的API。

解决方案

将 sass版本变更为 1.79.0

npm i sass@1.79.3

2.vite.config.js
添加配置：
silenceDeprecations:[‘legacy-js-api’]

    css: {preprocessorOptions: {scss: {additionalData: `@use "@/styles/theme.scss" as *;@use "@/styles/element/index.scss" as *;`,silenceDeprecations:['legacy-js-api']},},},
