How to update a single gem conservatively
Method 1
This method works when all dependencies for the update are already met.
Determine the version you want to update to
Change it directly in Gemfile.lock
- Run bundle install and verify if it was successful
Method 2
This approach is suitable when the gem has no shared dependencies with other gems.
- Identify the version you wish to update to.
- Add that specific version explicitly to the Gemfile like so:
'=1.2.3'
- Execute
bundle install
- Remove the explicit version number afterward
- Run
bundle install one more time
Method 3
This method should always deliver results.
- Execute
bundle update GEMNAME
- Check the changes using
git diff Gemfile.lock and manage any unwanted updates
- Undo undesired changes to
Gemfile.lock, leaving only the desired updates
- Verify by running
bundle install
Method 4
There have been speculations about updating a single gem via bundle update --source GEMNAME. However, this feature is not officially documented in Bundler and might be unstable due to potential dependency mismatches.
Exercise caution when using this method and review your Gemfile.lock changes carefully.
Method 5
Bundler >= 1.14 introduces a --conservative flag. Enabling this flag during bundle update GEM ensures that only the specified gem gets updated without affecting its dependent gems.
