error: failed to push some refs to 'git@github.com:xxx/xxx.git'hint:
Updates were rejected because the remote contains work that you dohint: not have locally.
This is usually caused by another repository pushinghint: to the same ref.
You may want to first integrate the remote changeshint: (e.g., 'git pull ...')
before pushing again.hint:
See the 'Note about fast-forwards' in 'git push --help' for details.
