What are some examples of Ruby Gemfile configurations?
An example of an AI chatbot conversation about Ruby Gemfile configurations and best practices.
Can you show me some examples of Ruby Gemfile configurations?
Sure! A basic Gemfile might look like this:
source 'https://rubygems.org'
gem 'rails', '~> 6.1'
gem 'pg'
gem 'puma'
This example specifies Rails and PostgreSQL as dependencies.
What if I want to include a specific version of a gem?
You can specify a version like this:
gem 'nokogiri', '1.10.10'
This ensures that version 1.10.10 of Nokogiri is used.
How do I add a gem for development only?
You can use the :group option:
gem 'rspec', group: :development
This will include RSpec only in the development environment.
Can I include gems from GitHub?
Yes! You can include gems from GitHub like this:
gem 'my_gem', git: 'https://github.com/username/my_gem.git'
This pulls the gem directly from the specified repository.
