Some ElementUI components are missing or not working when previewing after build.

Describe the bug

I created a project with vite and vue2 by create-vue, then I use this and unplugin-auto-import tools to import element-ui components. It's ok in development stage. But some element-ui components are missing or not working when previewing after build.

this is my vite config:

// vite.config.js
import { fileURLToPath, URL } from "node:url";

import { defineConfig } from "vite";
import legacy from "@vitejs/plugin-legacy";
import vue2 from "@vitejs/plugin-vue2";
import AutoImport from "unplugin-auto-import/vite";
import Components from "unplugin-vue-components/vite";
import { ElementUiResolver } from "unplugin-vue-components/resolvers";

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue2(),
    legacy({
      targets: ["ie >= 11"],
      additionalLegacyPolyfills: ["regenerator-runtime/runtime"],
    }),
    AutoImport({
      resolvers: [ElementUiResolver()],
    }),
    Components({
      resolvers: [ElementUiResolver()],
    }),
  ],
  resolve: {
    alias: {
      "@": fileURLToPath(new URL("./src", import.meta.url)),
    },
  },
});
