【问题讨论】：

旁注：您是否阅读过有关删除的文档？删除数据集有许多复杂性，不建议在客户端执行此操作。 docs

标签： angular typescript node-modules ionic4

【解决方案1】：

您似乎缺少一些/。请尝试以下操作：

this.afirestore.doc(`users/${this.user.getUID()}/AcBooking/${record_id}`).delete();

或者做：

return this.afirestore
  .collection('users')
  .doc(this.user.getUID())
  .collection('AcBooking')
  .doc(record_id)
  .delete()

这里我假设AcBooking 是一个集合。
