I just encountered a problem when merging a branch into master in git. First, I got the branch name by running
git ls-remote. Let's call that branch "branch-name". I then ran
git merge branch-name command and got the following result:
fatal: branch-name - not something we can merge
How do I resolve this error?
As shown in How does "not something we can merge" arise?, this error can arise from a typo in the branch name because you are trying to pull a branch that doesn't exist.
If that is not the problem (as in my case), it is likely that you don't have a local copy of the branch that you want to merge. Git requires local knowledge of both branches in order to merge those branches. You can resolve this by checking out the branch to merge and then going back to the branch you want to merge into.
git checkout branch-name
git checkout master
git merge branch-name
This should work, but if you receive an error saying
error: pathspec 'remote-name/branch-name' did not match any file(s) known to git.
you need to fetch the remote (probably, but not necessarily, "origin") before checking out the branch:
git fetch remote-name
