이 중 걱정해야 할 것이 있을까요? 몇 가지는 이전에 본 것 같아서 답은 '아니오’일 것 같지만, 확인해 주시면 좋겠습니다 🙂 감사합니다. ```plaintext 103:M 10 Feb 2022 14:23:47.564 # WARNING overcommit_memory is set to 0!

이 항목만 약간 걱정되긴 하지만, 모든 것이 정상적으로 작동한다면 무시해도 됩니다. ```plaintext Could not create server TCP listening socket *:6379: bind: Address already in use ``` 나머지는 모두 무해합니다. > [@Jonathan5](#): > > `Node v16.13.2 is not tested against Ember CLI on your platform. We recommend that you use the most-recent "Active LTS" version of Node.js` 하지만… 하지만… Node v16이 _[실제로](https://github.com/nodejs/Release#lts_schedule)_ Node.js의 “Active LTS” 버전입니다. ---

빠른 답변 감사합니다! _모든 것_이 제대로 작동하는지 확인할 처지는 아닙니다. 🙂 최소한 화면에 포럼이 정상적으로 표시되는 것만 확인하면 될까요? ---
