Instance Method Summary

Instance Method Details

#gemfile(install = false, options = {}, &gemfile)

Note:

Every gem that is specified in this ‘Gemfile’ will be required, as if the user had manually called ‘Bundler.require`. To avoid a requested gem being automatically required, add the `:require => false` option to the gem dependency declaration.

Allows for declaring a Gemfile inline in a ruby script, optionally installing any gems that aren’t already installed on the user’s system.

Examples:

Using an inline Gemfile

#!/usr/bin/env ruby

require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'
  gem 'json', require: false
  gem 'nap', require: 'rest'
  gem 'cocoapods', '~> 0.34.1'
end

puts Pod::VERSION # => "0.34.4"

Parameters:

  • install (Boolean) (defaults to: false) —

    whether gems that aren’t already installed on the user’s system should be installed. Defaults to ‘false`.

  • gemfile (Proc) —

    a block that is evaluated as a Gemfile.
