Here’s a short tip for all programmers out there: do not push by force to gem repo. Why?
If you maintain a gem (or a fork specifically for your app), do not push by force to the `master` branch, or actually any other branch that can be referenced in the app's `Gemfile`. It may cause you some trouble.
If your Shortgem is referenced via `git`, you can have a problem when someone (possibly you) pushes by force. When you push by force, your Gemfile.lock needs to be updated to reflect the commit change. Otherwise you will get an error: `fatal: Could not parse object 'some_commit_id'`.
To solve it, you need to re-generate the `Gemfile.lock`.
The easiest way to do it:
1. Comment the problematic gem in the `Gemfile`
2. Run `bundle install`
3. Uncomment the gem from the first step
4. Run `bundle install` once again.
Always ensure that shared branches (such as `master` or `develop`) are merge-only and set as protected on `Github` or `Gitlab`. Do you have any questions about this issue? Or any other IT-related problems? Contact iRonin for assistance!
