Question

我正在尝试在Windows 7 x64中进行捆绑安装，但在为ffi gem安装本机扩展时会出错。我的Gemfile没有ffi gem。唯一的依赖是'capybara'。

第二个奇怪的是，我的Gemfile中仅提到了水豚用于“测试”环境，但是当我进行“捆绑安装”时，应该使用开发环境。为什么它会解析“测试”部分？

source 'http://rubygems.org'
gem 'rake', '0.9.2.2'
gem 'rails', '3.2.1'

...

group :test do
  if RUBY_PLATFORM =~ /(win32|w32)/
    gem 'win32console'
  end
  ...
  gem 'capybara'
  ...
end

我可以安装以前版本的ffi，但是水豚需要新版本。
