项目中build 时候需要生成如下dist中的main.d.ts，

如果配置vite additionalData会造成预编译scss报错

preprocessorOptions: {scss: {additionalData: `@import "@/assets/styles/variables.scss";`,// 刚开始使用下面两个配置可以打包出来，但是会造成预编译scss报错，所以不能用// api: 'modern-compiler', // 使用现代API避免警告// silenceDeprecations: ['legacy-js-api'], // 忽略旧API的弃用警告}

所以要在vite配置

  plugins: [dts({// 指定 tsconfig 文件tsconfigPath: 'tsconfig.app.json',include: ['src/**/*.ts', 'src/**/*.tsx', 'src/**/*.vue'],rollupTypes: true,        // 合并为单个文件（如 main.d.ts）copyDtsFiles: true        // 确保复制所有关联的 .d.ts 文件}), tailwindcss()],

直接上正确配置
package.json

 "types": "./dist/vue3/main.d.ts","main": "./dist/vue3/moten.umd.cjs","module": "./dist/vue3/moten.js","exports": {".": {"types": "./dist/vue3/main.d.ts","import": "./dist/vue3/moten.js","require": "./dist/vue3/moten.umd.cjs"},"./style": {"import": "./dist/vue3/main.css","require": "./dist/vue3/main.css"},"./vue2": {"types": "./dist/vue2/main.d.ts","import": "./dist/vue2/moten.js","require": "./dist/vue2/moten.umd.cjs"},"./vue2/style": {"import": "./dist/vue2/main.css","require": "./dist/vue2/main.css"}},
