How do I manage different environments in my Rails Gemfile?

In your Rails Gemfile, you can specify gems for different environments using groups. For example, you can use group :development do to include gems only in the development environment.

Can you give me an example of how to set that up?

Sure! Here's a simple example:

source 'https://rubygems.org'

gem 'rails'

group :development do
  gem 'pry'
end

group :test do
  gem 'rspec-rails'
end

What if I want to include a gem in both development and test?

You can create a new group that includes both environments. For example:

group :development, :test do
  gem 'factory_bot_rails'
end

Is there a way to specify a gem version for different environments?

Yes, you can specify different versions for different environments by using conditional logic in your Gemfile. For example:

if Rails.env.development?
  gem 'some-gem', '~> 1.0'
else
  gem 'some-gem', '~> 2.0'
end
