my gemfile

source 'https://rubygems.org' gem 'rails', '3.2.13' # bundle border rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git' gem 'sqlite3' # gems used assets , not required # in production environments default. grouping :assets gem 'sass-rails', '~> 3.2.3' gem 'coffee-rails', '~> 3.2.1' # see https://github.com/sstephenson/execjs#readme more supported runtimes # gem 'therubyracer', :platforms => :ruby gem 'uglifier', '>= 1.0.3' end gem 'jquery-rails' # utilize activemodel has_secure_password # gem 'bcrypt-ruby', '~> 3.0.0' # utilize jbuilder templates json # gem 'jbuilder' # utilize unicorn app server # gem 'unicorn' # deploy capistrano # gem 'capistrano' # utilize debugger # gem 'debugger' gem 'nokogiri', '1.6.3.1 ruby java x64-mingw32 x86-mingw32'

there error in gemfile, , bundler cannot continue.

how can fixed issue?

this line: gem 'nokogiri', '1.6.3.1 ruby java x64-mingw32 x86-mingw32' makes bundler nokogiri version "1.6.3.1 ruby java x64-mingw32 x86-mingw32", not valid version.

i'm guessing want version "1.6.3.1", on platforms ruby, java, x64-mingw32 , x86-mingw32, specified gem 'nokogiri', '1.6.3.1', platforms: %i(ruby java x64-mingw32 x86-mingw32).

adding that, java, x64-mingw32 , x86-mingw32 not valid platforms, mean jruby , mingw respectively?
