What is a gem lockfile and why is it important?
A gem lockfile, typically named Gemfile.lock, is used in Ruby applications to ensure consistent gem versions across environments.
How does it differ from the Gemfile?
The Gemfile specifies the gems your application needs, while the Gemfile.lock locks those gems to specific versions.
What happens if I don't use a lockfile?
Without a lockfile, different environments might install different versions of gems, leading to potential compatibility issues.
Can I manually edit the Gemfile.lock?
It's not recommended to manually edit the Gemfile.lock, as it can lead to inconsistencies. Use bundle install
instead.
How do I update the gems in my lockfile?
You can update the gems by running bundle update
, which will update the Gemfile.lock with the latest compatible versions.
