尝试捆绑安装时出现错误。我在空项目中遇到同样的错误。

 Installing libv8 (3.3.10.4) with native extensions
   Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

    Could not create Makefile due to some reason, probably lack of
   necessary libraries and/or headers.  Check the mkmf.log file for more
       details.  You may need configuration options.

   An error occured while installing libv8 (3.3.10.4), and Bundler cannot continue.

    Make sure that `gem install libv8 -v '3.3.10.4'` succeeds before bundling.

这是我的 Gemfile：来源“https://rubygems.org”

  gem 'rails', '3.2.2'
  gem 'bootstrap-sass', '2.0.0'
  # Bundle edge Rails instead:
  # gem 'rails', :git => 'git://github.com/rails/rails.git'
   gem'devise'

  gem 'mysql2'

group :deployment do
 gem 'pg'
end

gem '活跃商家'

默认在生产环境中。组：资产做宝石'twitter-bootstrap-rails' 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'

 gem 'uglifier', '>= 1.0.3'
end

  gem 'jquery-rails'

【问题讨论】：

目前没有希望，因为 v8 不会在 windows 上构建。您可能还想要其中一个或另一个：bootstrap-sass、twitter-bootstrap-rails

【解决方案1】：

libv8 需要安装 Python 并将其添加到 Windows 路径中。

步骤
- 下载安装Python27
- 右击计算机->属性->高级设置->环境变量
- 在“系统变量”下找到路径并选择编辑
- 添加“c:\Python26;”

注意：我必须重新启动 Aptana 才能识别新的 Python 路径。
