无法安装 libv8 3.11.8.17 gem。我已经环顾四周，发现它不支持 Windows。虽然我仍在寻找解决方法？

Make sure that `gem install libv8 -v '3.11.8.17'` succeeds before bundling.

我不尝试使用 therubyracer，老实说，我不知道什么 gem 依赖于 libv8。安装 Python27 和设置 PATH 没有做任何事情。除了换平台还能做什么？或者也许有一个我似乎没有掌握的从https://github.com/hiranpeiris/therubyracer_for_windows获得的 v8.dll 的解决方法？

尝试这个

gem install libv8 -v '3.16.14.3' -- --with-system-v8

我只在我的 Linux 环境中在 prod 上使用 libV8 和 TheRubyRacer。我在 Gemfile 中将它们分开：

group :production do
 gem 'libv8', '~> 3.11.8.3'
 gem 'therubyracer', :platform => :ruby
end

然后我捆绑安装而不生产：

bundle install --without production

（参见 SO 文章：为什么 'bundle' 在我的开发机器上安装生产 gem？）

这似乎避免了关于 Windows 的整个 V8 辩论。
