병합 오류: refusing to merge unrelated histories, 푸시가 거부됨
결론 : intellij 터미널에서 git pull --allow-unrelated-histories
를 사용해서 병합 혹은 처리를 하면 된다.


hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
! refs/heads/master:refs/heads/master [rejected] (non-fast-forward)
hint: 'git pull ...') before pushing again.
Done
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

git push or pull 진행시 오류.
=> 내 저장소의 소스코드와 github의 소스코드의 기록을 비교했을때 차이가 심할때 병합 오류가 날꺼같으니 한번 확인해 봐라.
