Ruby - Gems and Bundler

You wrote gem 'rails', '~> 5.2.0' but bundler installs version 6.0.0. What is the likely cause?

AAnother gem requires rails 6.0.0 causing conflict resolution

BBundler ignores version constraints by default

CThe ~> operator was misused; it allows major version updates

DThe Gemfile syntax is incorrect

Step-by-Step Solution

Solution:

Step 1: Understand the ~> 5.2.0 constraint
This constraint allows versions >= 5.2.0 and < 5.3.0, so 6.0.0 should not be installed.
Step 2: Consider bundler dependency resolution
If bundler installs 6.0.0, it is likely due to another gem requiring rails 6.0.0, causing bundler to resolve to that version despite the constraint.
Final Answer:
Another gem requires rails 6.0.0 causing conflict resolution -> Option A
Quick Check:
Dependency conflicts can override constraints = Another gem requires rails 6.0.0 causing conflict resolution [OK]

Quick Trick: Check other gems' requirements when unexpected versions install [OK]
