Cannot use import statement outside a module

使用Vite3 官方SSR例子引入 v-viewer。在开发环境正常，生产打包浏览后出现此问题

初步判断是引入v-viewer时指向了es方式的入口index.es.js

  "main": "./dist/index.umd.js",
  "unpkg": "./dist/index.umd.js",
  "module": "./dist/index.es.js",

需要显式指定umd入口才能避免出现import语句

更新到3.0.11再试一下

低于3.0.11的版本可以禁用外部化

ssr: {
    noExternal: [
      'v-viewer'
    ]
  },
