깃허브, failed to push some refs to~,Updates were rejected because the remote contains work that you do not have locally 에러

깃허브에 로컬 프로젝트를 push해주려는 도 중 아래와 같은 에러가 발생했다.

$ git push -u origin master
To https://github.com/wkimdev/Node-js-Project
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://github.com/wkimdev/Node-js-Project'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

같은 레퍼지스토리에 push를 줬다는게 원인이라고 한다.

구글링 해보니 바로 해결법이 나온다.

나의 어설픈 해석,,;;

내 레퍼지스토리에 깃허브를 create할 때, new commit을 의미하는 README.md,를 만들게 된다.

내 로컬 레퍼지스토리는 아직 이 new commit을 모른다. 그렇기 때문에 

Updates were rejected because the remote contains work that you do not have locally.

위의 에러메세지를 던지게 된다.(깃 허브에 직접 레퍼지스토리를 만들고(readme까지 직접생성 했었음), 로컬에서 또 push해서 충돌이 일어남??)

간단한 해결 방법!

-f는 아마도 force강제 처리인 듯,,(?)

저 문장으로 실행하니 아래와 같이 push가 잘 된다!

$ git push -f origin master
