Do not push by force to gem repo - Ruby Developer’s Notes

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:
- Comment the problematic gem in the
Gemfile
- Run
bundle install
- Uncomment the gem from the first step
- 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!
