我有一个全新安装的ruby2.1.1，一组干净的gem，我用自制软件重新安装了V8，但我得到了这个‘无法识别的命令行选项’错误。

如果Ubuntu用户有这种情况(例如:在Ubuntu VM上)
gem install therubyracer -v '0.11.4'

我不得不运行brew更新，gcc。
brew upgrade gcc
==> Upgrading 1 outdated package, with result:
gcc 4.9.1

######################################################################## 100.0%
==> Pouring gcc-4.9.1.mavericks.bottle.2.tar.gz
==> Caveats
GCC has been built with multilib support. Notably, OpenMP may not work:

If you need OpenMP support you may want to
brew reinstall gcc --without-multilib

在MacOS10.10上，更改g++和gcc的符号链接对我很有效。
