我正在使用FreeBSd OS,当我尝试安装libv8时,

gem install libv8


它抛出一个错误...

Building native extensions.  This could take a while...
ERROR:  Error installing therubyracer:

我被遮住了

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


在宝石文件中..

最佳答案

这可能发生在Ruby 1.8.7中,它没有像1.9.x那样自动包含红宝石。 github中有更新:https://github.com/fractaloop/libv8/blob/master/ext/libv8/extconf.rb

但是,目前看来这还没有出现在已发布的宝石中。它应该像这样安装一样简单:

gem 'libv8', :git => 'git://github.com/fractaloop/libv8.git'


但是从源头上看,它动态地将gem版本与v8库的版本相关联,当我尝试使用它时,它失败了,说它是0.0.4版本。我使用的是其他操作系统,因此请尝试一下,看看它是否适合您。
