解决 error: failed to push some

Resolve error: failed to push some refs to 'https://github.com/

报错：

! [rejected] main -> main (fetch first)
error: failed to push some refs to 'https://github.com/XXX.git'

原因：远程库和本地库不一致。通常出现在初始化仓库有readme而本地没有等情况。

提示：git的提示同上。

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.

解决方法：

git pull --rebase origin master

原理：

把远程库中的更新合并到本地库中，–-rebase的作用是取消掉本地库中刚刚的commit，并把他们接到更新后的版本库之中。然后再进行push即可。

git pull -–rebase origin master 操作，意为先取消commit记录，并且把它们临时保存为补丁(patch)(这些补丁在”.git/rebase”目录中)，之后同步远程库到本地，最后合并补丁到本地库之中。

注意：距离上次push提交至今，在本地库commit的记录均暂存为patch。
