git push 错误处理

** 错误信息 **
错误1

fetch failed
cannot lock ref 'refs/remotes/origin/feature/xxx': unable to create lock file .git/refs/remotes/origin/feature/xxx.lock; non-directory in the way

错误2

Fetch failed: cannot lock ref 'refs/remotes/origin/Feature': there is a non-empty directory '.git/refs/remotes/origin/Feature' blocking reference 'refs/remotes/origin/Feature'

分析：
由于远程分支删除，导致本地ref指向的remote 分支不存在，fetch不匹配，从而报错

解决方法：

// 回收
git gc --prune=now
//更新remote
git remote update  --prune
//删除报错的路径
rm -rf .git/refs/remotes/
