Ruby - Gems and Bundler

You have updated the version constraints of gems in your Gemfile and want to ensure all machines use the exact same gem versions. Which Bundler command should you run to update the lock file accordingly?

Abundle update --lock

Bbundle install

Cbundle lock --update

Dbundle install --deployment

Step-by-Step Solution

Solution:

Step 1: Understand the role of the lock file
The Gemfile.lock records exact gem versions to ensure consistency across environments.
Step 2: Identify the correct command to update the lock file
Running bundle install after modifying the Gemfile updates the Gemfile.lock with resolved versions.
Step 3: Evaluate other options
bundle update updates gems to latest allowed versions but may change more than intended; bundle lock --update is not a valid command; bundle install --deployment installs gems using the lock file but does not update it.
Final Answer:
bundle install -> Option B
