Rails update only one gem with bundler Jun 6 2018
When we use:
1 bundle update specific_gem
We expect to only update one gem the one we are telling bundler to update but that is not the case it updates the gem and all its dependencies, and if the dependencies have updates but the gem doesn't the dependencies get updated no matter what.
so to avoid that use:
1 bundle update --source specific_gem
And that should do the trick.
