Some chunks are larger than 500 kB after minification. Consider:
- Using dynamic import() to code-split the application
- Use build.rollupOptions.output.manualChunks to improve chunking: https://rollupjs.org/configuration-options/#output-manualchunks
- Adjust chunk size limit for this warning via build.chunkSizeWarningLimit.

出现以上报错：
vite.config.ts

增加

   build: {
    chunkSizeWarningLimit: 1600,
  },

完整代码如下

import react from '@vitejs/plugin-react'
import path from "node:path"
import UnoCSS from 'unocss/vite'
import { defineConfig } from 'vite'

// https://vite.dev/config/
export default defineConfig({
  plugins: [react(), UnoCSS(),],
  resolve: {
    alias: {
      "@": path.resolve(__dirname, "./src"),
    },
  },
   build: {
    chunkSizeWarningLimit: 1600,
  },
})

完美解决！！！
