我正在尝试使用以下代码测试插入到 Mongodb Change 流中。只有这两行

client = pymongo.MongoClient(CONNECTION_STR)
print(client.changestream.collection.insert_one({"hello": "world"}).inserted_id)

运行此 python 文件时出现的错误如下，

Traceback (most recent call last):
  File "D:\PyMongo Change Streams\test.py", line 7, in <module>
    print(client.changestream.collection.insert_one({"hello": "world"}).inserted_id)

    raise ServerSelectionTimeoutError(
pymongo.errors.ServerSelectionTimeoutError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats,PY_SSIZE_T_CLEAN macro must be defined for '#' formats,PY_SSIZE_T_CLEAN macro must be defined for '#' formats

我还使用以下代码测试了连接，它运行良好并打印出数据库信息。

# try:
#     client = pymongo.MongoClient(CONNECTION_STR)
#     db = client.API
#     print(db)
# except Exception as e:
#     print(e)

谁能帮我解释一下这个错误？

ServerSelectionTimeoutError(
pymongo.errors.ServerSelectionTimeoutError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats,PY_SSIZE_T_CLEAN macro must be defined for '#' formats,PY_SSIZE_T_CLEAN macro must be defined for '#' formats

这是我第一次使用 MongoDB changestream。请帮我。先感谢您！
