我使用的是W7 64bit。简单地说,当我进入时:

C:\Sites>gem install libv8

我得到了这个结果:

Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing libv8:

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。

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,我也经历过这个问题

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'

gem 'therubyracer', :platforms => :ruby

因为Windows不需要或不喜欢那个gem。

答案 2 :(得分:1)

我遇到了与你描述的相同的Windows问题:

gem 'twitter-bootstrap-rails'

当我从github切换这个版本时:

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

没问题。试一试。
