libv8 gem（v3.3.10之后的所有版本）的安装失败，并显示消息“已杀死”。
我在我的Gemfile中包含了libv8和therubyracer：
group :production, :staging do
gem 'libv8'
gem 'therubyracer'
end
bundle update在本地可以正常运行（Mac OS X）。当我执行cap staging deploy时，部署失败并显示： * 2013-01-04 19:17:51 executing `bundle:install'

目前，我必须指定therubyracer和libv8的旧版本才能使部署成功：
group :production, :staging do
gem 'libv8', '~> 3.3.10'
gem 'therubyracer', '~> 0.10.2'
end
看来this Issue可能是相关的。
有解决办法吗？
最佳答案
事情在2013年1月7日进行了整理……但是一天后一切都崩溃了。在那之后的第二天，看起来一切又重新回到了一起！
therubyracer v0.11.1现在再次依赖于libv8 gem。因此，我的Gemfile已更改为：
group :production, :staging do
gem 'therubyracer'
end
这将安装最新版本的therubyracer（v0.11.1），以及最新版本的libv8（v3.11.8.13）。对我来说，这已经完全解决了问题-因此，therubyracer v0.11.1和libv8 v3.11.8.13 gem可以很好地安装了。
如果您不是这种情况，那么仍然有选择。对于仍然无法部署的Rails应用程序，我已经取得了成功：
group :production do
gem 'libv8', '3.11.8.10'
gem 'therubyracer'
end
也有可能（可能是更好的选择）坚持使用已知良好的版本，直到通过将Gemfile更改为以下方式来解决所有这些问题：
group :production do
gem 'therubyracer', '0.10.2'
end
