ruby-on-rails-3 - bundle install libv8 (therubyracer) 在 Windows 上安装失败(使用 native 扩展)

Question

我正在尝试在我的 Windows 机器上进行捆绑安装，并且我尝试包括以下两个 gem:

gem 'therubyracer'
gem 'libv8', '3.3.10.4'

但似乎都不起作用，这给我留下了这个错误:

有没有办法解决这个问题

查看语言依赖项:https://github.com/fractaloop/libv8/graphs/languages

您需要在计算机上安装 Python。完成后，我还会安装最新版本的 bundler :

gem install bundler --pre
