웹개발 3주차 3-12 mongoDB 연결하기 과정을 따라가는 중입니다.

dnspython, pymongo는 설치를 완료했습니다.

dbprac.py 을 만들고, pymongo 기본코드 붙여넣고, 강의에 따라서 작성했습니다.

mongoDB 웹페이지에서 connect to cluster - connect your application - driver : python - version : 3.6 or later 까지 지정하고, code 복사해서 붙여넣기까지 완료했습니다. password도 test로 바꾸어 작성했습니다.

from pymongo import MongoClient
client = MongoClient('mongodb+srv://sparta:test@cluster0.n9jkglo.mongodb.net/?retryWrites=true&w=majority')
db = client.dbsparta


doc = {
    'name' : '영수',
    'age' : 24
}
db.users.insert_one(doc)

저장하고 Run python file in terminal 누르니까 강의내용과는 달리, terminal 에 다음과 같은 내용이 달리면서 오류가 발생한 것 같습니다.

terminal 에 뜬 전체 내용을 복사해서 올리면, 아래와 같습니다.

오류가 나서 그런지, mongoDB 들어가도 data 저장이 안되어 있습니다. 도와주세요.
