Add this line to your application's Gemfile:

gem 'with_clean_rbenv'

And then execute:

$ bundle

Or install it yourself as:

$ gem install with_clean_rbenv

require 'with_clean_rbenv'

WithCleanRbenv.with_clean_rbenv do
  Dir.chdir '/path/to/other/ruby/project' do
    system('rbenv exec bundle exec ruby -v')
  end
end

# or short
WithCleanRbenv.within_clean_rbenv '/path/to/other/ruby/project' do
  system('rbenv exec bundle exec ruby -v')
end

If you need to set custom environment variables:

context = WithCleanRbenv::Context.new('GEM_HOME' => nil)

context.with_clean_rbenv do
  system('rbenv exec bundle exec ruby -v')
end

If you want to replace default context:

# Replace default context.
WithCleanRbenv.current = WithCleanRbenv::Context.new('GEM_HOME' => nil)

WithCleanRbenv.with_clean_rbenv do
  system('rbenv exec bundle exec ruby -v')
end
