“Not something we can merge” in Git is a common error message that can occur due to various reasons. One of the most common mistakes leading to this error is a typo in the branch name when attempting to pull a branch that does not exist. If this is not the issue, it is likely due to not having a local copy of the branch that you are trying to merge with. In this article, we will delve deeper into the causes of this error message and how to troubleshoot it.”
Understanding Git’s “Not Something We Can Merge” Error
When working with Git, it is common to encounter the error message “Not something we can merge”. This error message typically arises from two different situations.
Conflicting Changes
One situation that can trigger the “Not something we can merge” error message is conflicting changes in different branches of the same Git repository. This can happen when two or more developers make changes to the same file in different branches. When attempting to merge these branches, Git will detect the conflict and prevent the merge. To resolve this issue, you must manually resolve the conflict by modifying the file and creating a new commit. Once the conflict is resolved, you can attempt the merge again.
Non-Fast-Forward Merges
The second situation that can trigger the “Not something we can merge” error message is non-fast-forward merges. A non-fast-forward merge occurs when the head of the branch you’re trying to merge is not a direct descendant of your current branch. This can happen when another developer has created a new branch from an older commit and made changes that haven’t been merged into the original branch. In this case, Git will prevent the merge and display the “Not something we can merge” error message. To resolve this issue, you must update your local copy of the branch by fetching the changes that were made and merging them into your current branch. Once you’ve updated your local copy of the branch, you can attempt the merge again.
How to Fix Git’s “Not Something We Can Merge” Error
Git is a powerful version control system used by developers to manage their code effectively. However, when multiple people are working on the same project, conflicts may arise, causing the “Not Something We Can Merge” error to occur. Here are some practical solutions to resolve the error message and get back to working with Git.
Option 1: Using –force
If you’re sure that your changes do not conflict with those of others, you can use the “–force” option to overwrite conflicting changes and merge non-fast-forward branches. This option is not recommended for regular use as it can cause you to lose important changes. Instead, it should be used sparingly and with caution.
Option 2: Resolving Conflicting Changes
When multiple people are working on the same project, it’s common to have conflicting changes that need to be resolved manually. To do this, you can use a Git tool such as a merge tool or the “git mergetool” command. Alternatively, you can resolve the conflicts manually, which involves reviewing the changes made by each person and deciding which ones to keep. Once the conflicts have been resolved, you can then merge non-fast-forward branches.
Best Practices to Avoid Git’s “Not Something We Can Merge” Error
Git’s “Not Something We Can Merge” error message can be troublesome, but there are ways to prevent encountering this problem in the first place. Here are some best practices to follow:
Regularly Pulling and Pushing Changes
To avoid conflicting changes and non-fast-forward merges, it’s crucial to regularly pull and push changes. This helps in ensuring that all team members have the most updated version of the code. By doing this, it reduces the probability of encountering conflicts because members have a unified understanding of the current state of the repository.
Communicating with Your Team
It’s essential for team members to communicate with each other before starting to make changes to the code to prevent conflicts. This applies especially when working simultaneously on the same file.
By communicating with your team, members will be aware of who’s going to modify, add, or delete specific lines or portions of the code. This helps avoid the team members from overwriting each other’s changes and encountering the “Not Something We Can Merge” error message.
Conclusion
The “Not Something We Can Merge” error in Git can be caused by various factors, such as a typo in the branch name or the absence of a local copy of the branch to be merged. To resolve this error, you must identify the root cause and take the necessary steps, such as creating a new branch, resolving merge conflicts with a new commit, or reverting pushed commits. Additionally, practicing best Git coding and troubleshooting practices and using commands like git log –merge and git diff can help prevent repeated merge conflicts and other common Git mistakes. By being aware of these solutions and using them effectively, you can experience smoother, more efficient Git workflows and avoid the “Not Something We Can Merge” error.

If you encounter the “not something we can merge” error, it may be due to a typo in the branch name or a lack of a local copy of the branch you want to merge. Another common cause is a merge conflict, which occurs when changes made to the same file conflict with each other. In this case, you need to resolve the conflict before merging the branches.
To avoid such errors, it is best to use Git’s merge tools and follow best practices such as discarding local file modifications, cleaning up local commits before pushing, and avoiding repeated merge conflicts. Familiarizing yourself with Git Hooks, which can help automate some of these best practices, can also be helpful.
