我在CentOS6.7中遇到gem安装错误
但是当我使用gcc -version时，它显示gcc的版本是4.4.7。
以下是错误信息：
Gem :: Ext :: BuildError：错误：无法构建gem原生扩展。

libv8 maintainer here.
Could you please try again after updating libv8 to the latest 3.16 version available?
If you continue receiving an error, please consider opening an issue with more info about your system and the gcc --version output of your compiler in libv8's issue tracker: https://github.com/cowboyd/libv8/issues
As a side note, you should consider asking the maintainers of a project directly first, through their issue tracker for example, before shooting a question in SO. Your question probably would have remained unanswered had I not been by chance looking for recent questions about libv8 here.
