Question

我是mongodb和pymongo的新手。昨天对于一个小项目，我开始测试nosql的感觉。但是，由于服务器选择超时错误，我无法执行任何操作

这是整个代码

import pymongo

client = pymongo.MongoClient("mongodb://localhost:27017/")

ContactsDB = client["ContactsDB"]

ContactsCollection = ContactsDB["ContactsCollection"]

to_insert = { "name": f"{name}", "phone": f"{phone}"}

ContactsCollection.insert_one(to_insert)

这是错误

  File "main.py", line 20, in add_contact
    x = ContactsCollection.insert_one(mydict)
  File "/home/erfan2003/.local/lib/python3.6/site-packages/pymongo/collection.py", line 700, in insert_one
    session=session),
  File "/home/erfan2003/.local/lib/python3.6/site-packages/pymongo/collection.py", line 614, in _insert
    bypass_doc_val, session)
  File "/home/erfan2003/.local/lib/python3.6/site-packages/pymongo/collection.py", line 602, in _insert_one
    acknowledged, _insert_command, session)

  File "/usr/lib/python3.6/contextlib.py", line 81, in __enter__
    return next(self.gen)
  File "/home/erfan2003/.local/lib/python3.6/site-packages/pymongo/mongo_client.py", line 1611, in _tmp_session
    s = self._ensure_session(session)

    return self.__start_session(True, causal_consistency=False)
  File "/home/erfan2003/.local/lib/python3.6/site-packages/pymongo/mongo_client.py", line 1551, in __start_session
    server_session = self._get_server_session()
  File "/home/erfan2003/.local/lib/python3.6/site-packages/pymongo/mongo_client.py", line 1584, in _get_server_session
    return self._topology.get_server_session()
