Some of your uncommitted changes would be overwritten by syncing.Please commit your changes then try

1. 解决方法有三种，在GitHub shel中输入以下命令，任选一种方法就能解决问题

    git reset --hard HEAD

   
   
   

    -- Destructive. When you do this you'll throw away everything you've done up to that point and be back at the last HEAD before you made any changes.

2. git commit 

   
   
   

   -- In the middle. With this you're committing your changes which will get rid of the error but if the changes aren't complete its probably superfluous.

3. git stash -u 

   
   
   

   -- My recommendation. With this you're able to "stash" or set aside the changes you've made up until this point. Then you can pull from a remote without interfering. Once you've done that you can run a git stash pop which will put back all of the changes you've made (without committing them).
