修复小牛的therubyracer / libv8（0.12.1）安装 [英] Fix therubyracer/libv8 (0.12.1) installation on Mavericks
本文介绍了修复小牛的therubyracer / libv8（0.12.1）安装的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
好的，我在这个系列的最后。有几个类似的问题，但他们都指的是0.10版的therubyracer，他们大多认为问题可以通过升级到0.12来解决。
我有类似的问题，但是当我使用0.12。
类似的问题
我在使用'standard'时遇到问题（xcode？ ）gcc，以及来自自制软件的apple-gcc42和gcc。我试过 --with-system-v8 和 - without-system-v8 ，再次，没有骰子。
以下是一些日志：

好的。因此，为了解决与therubyracer 0.10有关的问题，一些人推荐brew安装v8，然后告诉rubygems使用系统v8。让我们看看会发生什么！

OK, I’m at the end of my tether with this. There are a few similar questions but they all refer to therubyracer 0.10, and they mostly conclude that the problem can be fixed by upgrading to 0.12.
I’m having similar problems, but when I use 0.12.
Similar questions
I’m having problems using ‘standard’ (xcode?) gcc, and both apple-gcc42 and gcc from homebrew. I’ve tried both --with-system-v8 and --without-system-v8, and again, no dice.
Here’s some logs:

OK. So to fix the issues with therubyracer 0.10, some people recommend brew installing v8, then telling rubygems to use system v8. Let’s see what happens!
$ brew install v8
