therubyracer安装错误 [英] therubyracer install error

问题描述

正如你在下面看到的，libv8安装正常，但是therubyracer没有。我使用的是Mac 10.7.4。

解决方案

您可以使用brew中的Libv8而不是gem中的Libv8，您可以通过以下命令执行此操作：

 $ gem uninstall libv8 
 $ brew install v8 
 $ gem install therubyracer 
  

As you can see below, libv8 installs fine, but therubyracer doesn't. I'm using Mac 10.7.4.

解决方案

You can use the Libv8 from the brew instead of the one from gem. You can do that by following commands:

$ gem uninstall libv8
$ brew install v8
$ gem install therubyracer
