Node.js ReferenceError:未定义google通用SSR npm运行服务器：SSR

我知道google引用错误出现的原因，因为在服务器上执行的sever.js没有在其作用域中定义google。我正在寻找一个转机来修复这个错误

运行

npm后运行service:ssr

它会得到这个

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。在节点级别导入google的任何转变都会有所帮助。是否有任何

包

或

模块

可以帮助我
