推荐答案

您无法在Cloud Firestore中创建空集合.要解决此问题，您应该在该集合中至少创建一个文档.这样，该特定集合将开始存在.

There is no way you can create an empty collection in Cloud Firestore. To solve this, you should create at least one document within that collection. In this way, that particular collection will start to exist.

如果您在Firebase控制台中创建一个包含一个文档的集合，则将自动为您创建该集合.如果您尝试删除集合中的最后一个文档，也会发生这种情况，该特定集合将被自动删除.

If you create a collection in the Firebase Console containing one document, the collection is created automatically for you. This is also happening if you try to delete the last document in a collection, that particular collection will be automatically deleted.
