oh-my-zsh 更新

当无论是自动更新还是手动upgrade_oh_my_zsh更新oh-my-zsh时，出现下面提示：

Updating Oh My Zsh
error: cannot pull with rebase: You have unstaged changes.
error: please commit or stash them.
There was an error updating. Try again later?

这是因为修改了oh-my-zsh的git文件，可以使用如下方式更新：

> cd ~/.oh-my-zsh
> git status
> git stash
> upgrade_oh_my_zsh
> git stash pop
