[Solved] Vue3 Error: Cant find variable: GlobalThis

After the project is packaged, use a browser with a lower version to open it and report an error

Solution
Vue config.js

import { defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';
import legacy from '@vitejs/plugin-legacy';

// https://vitejs.dev/config/
export default defineConfig({
  base: './',
  plugins: [
    vue(),
    legacy({
      targets: ['> 1%, last 1 version, ie >= 11'],
      additionalLegacyPolyfills: ['regenerator-runtime/runtime'],
    }),
  ],
});
