试图安装libv8,"无法构建gem原生扩展"

Question

我使用的是W7 64bit.简单地说,当我进入:

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.

    C:/RailsInstaller/Ruby1.9.3/bin/ruby.exe extconf.rb

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.

卸载并重新安装不起作用.

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,我现在意识到此错误中列出的文件路径为/ usr/bin/env.这太奇怪了.

Answer 1

解决方案是安装版本.0

gem install libv8 --version 3.11.8.0

直到这个问题得到解决,我也经历过这一点

Answer 2

我遇到了这个问题,上面的@xiy让我得到了答案.不得不改变

gem 'therubyracer'

至

gem 'therubyracer', :platforms => :ruby

因为Windows不需要或不喜欢那个宝石.

Answer 3

我遇到了与您描述的相同的 Windows 问题：

gem 'twitter-bootstrap-rails'

当我从 github 切换版本时：

gem 'twitter-bootstrap-rails', :github => 'seyhunak/twitter-bootstrap-rails'

没问题。试一试。
