解决了吗？我也有

针对您提到的 uni-app 中的 DEPRECATION WARNING 关于 Dart Sass 的旧版 JS API 即将被移除的问题，这里提供一个解决方案的示例，展示如何在项目中迁移至 Dart Sass 的新 API。由于 uni-app 本身不直接处理 Sass 编译，但通常会通过 Webpack 或类似的构建工具来集成 Sass 编译，以下示例将基于一个典型的构建配置进行调整。

步骤 1: 更新 package.json

首先，确保您的项目中安装了最新版本的 sass 和 sass-loader。在 package.json 中更新这些依赖：

"dependencies": {
    "sass": "^1.43.0",  // 确保版本兼容 Dart Sass 1.x
    // 其他依赖...
},
"devDependencies": {
    "sass-loader": "^12.3.0",  // 确保版本与 Webpack 兼容
    // 其他开发依赖...
}

然后运行 npm install 或 yarn 来更新依赖。

步骤 2: 修改 Webpack 配置

在 uni-app 项目中，Webpack 配置通常位于 vue.config.js 或自定义的 Webpack 配置文件中。您需要确保 sass-loader 使用 Dart Sass 而不是 Node Sass。由于 Dart Sass 已经是 sass 包的默认实现，通常不需要额外配置，但确认 sass-loader 的选项正确无误：

// vue.config.js 或 webpack.config.js
module.exports = {
    css: {
        loaderOptions: {
            sass: {
                // Dart Sass 不需要额外的 implementation 选项
                // 但可以配置其他 Sass 选项，如全局变量
                additionalData: `@import "@/styles/variables.scss";`
            }
        }
    },
    // 其他配置...
};

步骤 3: 迁移旧版 JS API

如果您的 Sass 文件或构建脚本中使用了 Dart Sass 的旧版 JS API（例如通过 node-sass 的 render 方法），您需要迁移到 Dart Sass 的新 API。以下是一个旧版 API 到新 API 的迁移示例：

旧版 API（Node Sass）:

const sass = require('node-sass');
sass.render({file: 'input.scss'}, function(err, result) {
    if (!err) {
        console.log(result.css.toString());
    }
});

新版 API（Dart Sass）:

const sass = require('sass');
sass.render({file: 'input.scss'}, function(err, result) {
    if (!err) {
        console.log(result.css.toString());
    }
});

注意，API 调用在 Dart Sass 中几乎保持不变，主要的变化在于依赖包的名称从 node-sass 变为 sass。

通过以上步骤，您应该能够解决 DEPRECATION WARNING 并为 Dart Sass 2.0.0 的到来做好准备。如果 uni-app 项目中有特定的构建配置或插件处理 Sass，请根据实际情况调整上述步骤。
