This error message occurs when you try to merge two branches that do not have a common ancestor. This can happen when you are trying to merge two repositories that were created independently.
To resolve this error, you need to specify the ‘–allow-unrelated-histories’ option when running the ‘git merge’ command. This option allows Git to merge the unrelated histories.
Here are the steps to resolve the error:
- Switch to the branch that you want to merge into. For example, if you want to merge branch ‘dev’ into ‘master’, switch to the ‘master’ branch.
$ git checkout master
- Run the ‘git merge’ command with the ‘–allow-unrelated-histories’ option and specify the branch that you want to merge.
$ git merge --allow-unrelated-histories dev
Resolve any conflicts that occur during the merge.
Commit the changes and push them to the remote repository.
$ git commit -m "Merged dev branch"
$ git push origin master
Note: Be cautious when merging unrelated histories, as there may be conflicts or unexpected results. It is recommended to review the changes carefully before committing them.
