ruby-on-rails - 尝试安装libv8， "failed to build gem native extension"

我正在使用W7 64bit。简而言之，当我输入以下内容时:

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.

Gem files will remain installed in C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9
.1/gems/libv8-3.11.8.3 for inspection.

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的依赖项。

编辑:正如我所说，我在Windows上，并且我现在意识到在此错误中列出的文件路径为/usr/bin/env。所以这很奇怪。

最佳答案

解决方法是安装.0版

gem install libv8 --version 3.11.8.0

直到我解决了这个问题，
