我在我的本地分支上运行git pull以获取新分支，但出现错误：
warning: There are too many unreachable loose objects; run 'git prune' to remove them.
然后我checkout转到了新的分支，但每个文件都消失了。我尝试运行git prune，git gc并删除.git / .gc_log但没有运气。

答案 0 :(得分：0)
你的分支在7个提交后面是'origin / master'，可以快进。
如果您的local/master没有重要提交但尚未推送，那么您可以使用local/master 硬重置 origin/master。
$ git checkout master
$ git reset --hard origin/master
是否可以删除本地的所有内容并提取新的副本？
说，您想要将本地feature分支与您的origin/feature分支同步。然后，首先删除当前的本地feature分支，然后创建一个新的feature分支，其中包含origin/feature个历史记录。
$ git checkout master
$ git branch -D feature # delete local 'feature' branch
$ git fetch
$ git checkout -b feature origin/feature # create new feature = origin/feature
注意：将feature替换为本地分支的名称
