ReferenceError: google 未定义 Angular Universal SSR npm run server:ssr

Question

我知道 google 引用错误出现的原因是因为在服务器上执行的 sever.js 没有在其范围内定义 google 。我正在寻找解决方案来修复此错误。

运行后npm run serve:ssr得到这个

task: ZoneTask {
    _zone: Zone {
      _parent: [Zone],
      _name: 'angular',
      _properties: [Object],
      _zoneDelegate: [ZoneDelegate]
    },
    runCount: 0,
    _zoneDelegates: null,
    _state: 'notScheduled',
    type: 'microTask',
    source: 'Promise.then',
    data: ZoneAwarePromise [Promise] {
      __zone_symbol__state: 0,
      __zone_symbol__value: ReferenceError: google is not defined

    },

    invoke: [Function]

`

我需要在 server.ts 中使用有效值定义 google 以避免此错误。任何在节点级别导入 google 的转变都会有所帮助。有没有什么package可以module帮助我的
