使用Git推送代码时出错

我正在使用Git将代码上传到Gitlab，但它抛出了一些错误，如下所示

subrajyoti@subrajyoti-H81M-S:/opt/lampp/htdocs/MeetingRoomBooking/mrb_correct$ git push --all
Password for 'https://Subhraj@git-cms.securecodewarrior.com': 
To https://Subhraj@git-cms.securecodewarrior.com/Subhraj/Meeting-room-booking.git
 ! [rejected]        secure -> secure (fetch first)
error: failed to push some refs to 'https://Subhraj@git-cms.securecodewarrior.com/Subhraj/Meeting-room-booking.git'
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.
subrajyoti@subrajyoti-H81M-S:/opt/lampp/htdocs/MeetingRoomBooking/mrb_correct$

在此之前，我已将代码上载到我的存储库中。之后，我需要在cms.securecodewarrior.com中创建一些挑战，当我运行下面的命令时，它给出了上面的错误

1-git checkout -b secure

2-git push --all

正如错误所述，有些代码不在本地副本中。

尝试从远程存储库中提取并将其与本地副本合并，然后再次推送。

可能重复的可能重复的可能重复的我尝试了，但出现了相同的错误消息。您签出了哪个分支？我确实喜欢先从remote拉，然后再推送，但仍然是相同的错误。如果您确定回购协议不包含任何您需要的内容，则可以尝试git push-f，它将强制推送
