在使用git提交代码时会出现error: failed to push some refs to 'xxxx的错误

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.

原来使用的提交命令是git push -u origin 分支名

不妨尝试一下使用覆盖提交的方式

git push -f origin 分支名

其中“-f”是覆盖提交的参数。

大致意思是要先拉一下代码，再推一次代码，拉代码使用git push

先命令：git pull

后命令：git push

git pull origin master --allow-unrelated-histories

git commit -m 'xx'
