用于 Python 的 Firebase-admin sdk 引发错误“StreamGenerator”不可迭代

Question

之前（一周前）我与 Firestore 通信的 Python 代码工作得很好。但今天我又开始研究它，它在迭代

collection.stream()

时引发错误

    service_account = credentials.Certificate('credential/serviceAccount.json')
    firebase_admin.initialize_app(service_account)

    firestore_db = firestore.client()

    docs = firestore_db.collection("FeatureCollection").stream()
    for doc in docs:
        print(doc)

错误出现在

for doc in *docs*

。 错误是

"StreamGenerator" is not iterable "__next__" method not defined on type "DocumentSnapshot"

。

此外，每当我执行文档请求时，例如

doc = firestore_db.collection("FeatureCollection").document("geom1").get()

它还引发了关于 gRPC 的错误，我根本不熟悉。

找到解决方案了，和这个问题一样。

我必须设置一些环境变量：

export GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=1

export GRPC_PYTHON_BUILD_SYSTEM_ZLIB=1
