ruby-on-rails – 尝试安装libv8“无法构建gem本机扩展”

我正在使用W7 64位.简单地说,当我输入：

C:\Sites>gem install libv8

我得到这个结果：

Temporarily enhancing PATH to include DevKit...
Building native extensions.  This Could take a while...
ERROR:  Error installing libv8:
ERROR: Failed to build gem native extension.

卸载和重新安装不起作用.

我正在尝试安装libv8,因为它是twitter-bootstrap-rails的依赖.

编辑：正如我所说,我在Windows上,现在我意识到这个错误中列出的文件路径是/usr/bin/env.这很奇怪

解决方法

解决方案是安装版本.0

gem install libv8 --version 3.11.8.0

直到这是固定的,因为我也经历过这个
