이렇게 vscode로 server.js를 작성하고 저장하고 여기서 터미널(파워쉘)을 열었습니다.
npm install mongodb@3.6.4는 했습니다.
nodemon server.js를 입력하니 오류가 납니다.
https://haerim95.tistory.com/50 이 글 보고 해결하려 했는데 그냥 시작 누르고 나오는 터미널에서해봐도 안됩니다
-----밑이 오류 내용-----
(node:18056) Warning: Accessing non-existent property 'MongoError' of module exports inside circular dependency
(Use `node --trace-warnings ...` to show where the warning was created)
(node:18056) DeprecationWarning: current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.
위 오류들은 무시해도 된다지만 혹시 몰라서 적어봅니다.
