Step-by-Step Solution
Solution:
Step 1: Interpret the '~> 1.10.0' constraint
This means versions >= 1.10.0 and < 1.11.0 are allowed.Step 2: Check each version against the range
Version 1.9.0 is less than 1.10.0 (not allowed). 1.10.5 is between 1.10.0 and 1.11.0 (allowed). 2.0.0 is greater than 1.11.0 (not allowed). 1.11.0 is equal to the upper bound (not allowed).Final Answer:
1.10.5 -> Option BQuick Check:
~> 1.10.0 allows 1.10.x but not 1.11.0 [OK]
Quick Trick: ~> locks last digit, allows patch updates only [OK]
Common Mistakes:
- Allowing versions equal to upper bound
- Confusing minor and patch version limits
- Assuming major version updates allowed
