当我试图在终端中拉入我的项目目录时,我看到以下错误:
harsukh@harsukh-desktop:~/Sites/branch1$ git pull origin master
U app/config/app.php
U app/config/database.php
U app/routes.php
Pull is not possible because you have unmerged files.
Please, fix them up in the work tree, and then use 'git add/rm <file>'
as appropriate to mark resolution, or use 'git commit -a'.
为什么git说“拉是不可能的,因为你有未合并的文件”,我该如何解决它?
