What are Gemfile versions in Ruby?
Gemfile versions specify the versions of gems your Ruby application depends on, ensuring compatibility.
How do I specify a version in my Gemfile?
You can specify a version using syntax like gem 'rails', '6.1.0'
or use operators like ~> 6.1
.
What happens if I don't specify a version?
If you don't specify a version, Bundler will install the latest version of the gem, which may lead to compatibility issues.
