我在StackOverflow上搜索了类似的问题，但似乎总是有人试图从其分支机构升级为master。对我来说恰恰相反。我在master上，试图结帐到已经推送的分支。
当我这样做时：
git checkout mybranch
我得到：
error: Your local changes to the following files would be overwritten by checkout:
db/structure.sql
Please commit your changes or stash them before you switch branches.
Aborting
我尝试过：
git checkout -f mybranch
但我收到消息：
error: Entry 'db/structure.sql' not uptodate. Cannot merge.
如果我尝试隐藏或提交，则没有区别：
git stash
No local changes to save
git checkout mybranch
error: Your local changes to the following files would be overwritten by checkout:
db/structure.sql
Please commit your changes or stash them before you switch branches.
Aborting
或
git commit
On branch master
Your branch is up to date with 'origin/master'.
nothing to commit, working tree clean
git checkout mybranch
error: Your local changes to the following files would be overwritten by checkout:
db/structure.sql
Please commit your changes or stash them before you switch branches.
Aborting
git submodule status不返回任何内容，而git status -u返回：
On branch master
Your branch is up to date with 'origin/master'.
nothing to commit, working tree clean
有关如何解决此问题的任何建议？
