Pull is not possible because you have unmerged files, git stash doesn't work. Don't want to commit

问题

I just want to pull. I have changes to disregard, my Gemfile and Gemlock files and I'd be happy to just overwrite them and just pull. I tried stashing my changes away, this didn't work out for me. What do I do?

git pull
M   Gemfile
U   Gemfile.lock
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'.
~/projects/sms/apps2/apps2_admin(apps2)$ git stash save "saved"
Gemfile.lock: needs merge

回答1:

You can use git checkout <file> to check out the committed version of the file (thus discarding your changes), or git reset --hard HEAD to throw away any uncommitted changes for all files.

回答2:

git fetch origin
git reset --hard origin/master
git pull

Explanation:

• Fetch will download everything from another repository, in this case, the one marked as "origin".
• Reset will discard changes and revert to the mentioned branch, "master" in repository "origin".
• Pull will just get everything from a remote repository and integrate.

See documentation at http://git-scm.com/docs.

I've tried both these and still get failure due to conflicts. At the end of my patience, I cloned master in another location, copied everything into the other branch and committed it. which let me continue. The "-X theirs" option should have done this for me, but it did not.

git merge -s recursive -X theirs master

error: 'merge' is not possible because you have unmerged files. hint: Fix them up in the work tree, hint: and then use 'git add/rm ' as hint: appropriate to mark resolution and make a commit, hint: or use 'git commit -a'. fatal: Exiting because of an unresolved conflict.

I've had the same error and I solve it with: git merge -s recursive -X theirs origin/master
