【问题描述】：
尝试安装 therubyracer gem 后出现以下错误。
当我已经下载了 gem 时，不知道为什么它抱怨 v8。
我最初在安装 libv8 时遇到了麻烦，但后来设法使用 --system-v8 标志进行安装，但现在它的 rubyracer 抱怨。
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

and *not* the one that is bundle with the libv8 rubygem. However,
it could not be located. please make sure you have a version of
v8 that is compatible with 3.11.8.17 installed. You may
need to special --with-v8-dir options if it is in a non-standard
location

【问题讨论】：
-
我相信目前它不适用于 Chrome OS，因为它甚至不适用于 Windows（尽管 git 上提供了一些 gem 来提供 v8.dll 和其他支持）
-
gem "therubyracer", :require => 'v8' 将此添加到 gemfile 并检查
