找不到寶石 'refinerycms - 博客（〜> 2.1.0）紅寶石'

我已生成使用refinerycms myapp，
和註釋掉gem 'refinerycms-blog', '~> 2.1.0'
提出以下errror找不到寶石 'refinerycms - 博客（〜> 2.1.0）紅寶石'

Could not find gem 'refinerycms-blog (~> 2.1.0) ruby' in the gems available on this machine.

我的Gemfile的應用程序：

source 'https://rubygems.org' 

gem 'rails', '3.2.13' 

# Bundle edge Rails instead: 
# gem 'rails', :git => 'git://github.com/rails/rails.git' 

group :development, :test do 
    gem 'sqlite3' 
end 


# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
    # gem 'therubyracer', :platforms => :ruby 

    gem 'uglifier', '>= 1.0.3' 
end

# gem 'refinerycms-search', '~> 2.1.0' 
# gem 'refinerycms-page-images', '~> 2.1.0'

UPDATE：
更改爲2.0.5版本，並提高了以下

Bundler could not find compatible versions for gem "refinerycms-core": 
    In Gemfile: 
    refinerycms-blog (~> 2.0.5) ruby depends on 
     refinerycms-core (~> 2.0.3) ruby 

    refinerycms (~> 2.1.0) ruby depends on 
     refinerycms-core (2.1.0)
