把vite打包以后的js,css和img资源分别分门别类在js/css/img文件夹中：

//由于是处理打包以后的资源，所以需要配置build选项
export default defineConfig({
  plugins: [
    vue(),
    styleImport({
      resolves: [VantResolve()]
    })
  ],
  resolve: {
    alias: [
      { find: '@', replacement: resolve(__dirname, 'src') }
    ]
  },
  build: {
    assetsDir: 'static',
    rollupOptions: {
      input: {
        index: resolve(__dirname, 'index.html'),
        project:resolve(__dirname,"project.html")
      },
      output: {
        chunkFileNames: 'static/js/[name]-[hash].js',
        entryFileNames: 'static/js/[name]-[hash].js',
        assetFileNames: 'static/[ext]/name-[hash].[ext]'
      }
    }
  }
})

配置完成后打包：npm run build 发现出错：

Could not resolve entry module (project.html).
error during build:
Error: Could not resolve entry module (project.html).

 把build配置项的input第二项删去即可。

rollupOptions: {
      input: {
        index: resolve(__dirname, 'index.html')
      },
      output: {
        chunkFileNames: 'static/js/[name]-[hash].js',
        entryFileNames: 'static/js/[name]-[hash].js',
        assetFileNames: 'static/[ext]/name-[hash].[ext]'
      }
    }
