rake aborted 无法加载此类文件 --v8 windows

Question

请帮忙，这是我的 gemfile。这是我在 ubuntu 12.04 上创建的旧项目，现在我正在尝试在 Windows 8 上运行它。

来源'https://rubygems.org'

gem 'rails', '3.2.13'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'pg'
gem 'devise', '2.2.4'
gem 'execjs', :git => 'git://github.com/kennyj/execjs.git', :branch => 'rails_issue_2880'

# 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 'twitter-bootstrap-rails'
  gem 'less-rails'
  gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'

命令提示符：

C:\Users\manu\Documents\projets\rails\xibart>rake db:migrate
[WARNING] Please install gem 'therubyracer' to use Less.

取消注释 ruby​​ racer 线以安装它：

gem 'therubyracer', :platforms => :ruby
