我正在尝试在Mavericks上安装以下gem版本
(0.12.1) (0.12.1)
显然,竞技者的宝石依赖于libv8。
1)安装libv8
什么是libv8?我的一点研究似乎表明它是Google Chrome使用的某种javascript库?
我在安装它时遇到了问题,但是this great post有我的错误和关于如何绕过它的一个很好的解释的答案。
所以我在安装libv8
的时候
gem install libv8 -- --with-system-v8
据我所知,这将安装gem,但使用我的本地系统安装的v8库,而不是...gem附带的版本是什么?无论哪种方式,它都是成功的。
2)安装therubyracer
在下一步中,我在安装therubyracer
gem时遇到了问题。我不太确定这个gem是做什么的,只知道它是我正在尝试bundle install
的一个rails项目的依赖项。
它给出了以下错误:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

and *not* the one that is bundled with the libv8 rubygem. However,
it could not be located. please make sure you have a version of
v8 that is compatible with 3.16.14.3 installed. You may
need to special --with-v8-dir options if it is in a non-standard

据我所知,我选择使用我本地的V8库安装libv8
,而不是使用libv8
提供的库,但现在无法定位本地安装。
extconf.rb
?我在几个地方见过它。到底想用gcc
编译器做什么呢?
谢谢!!
编辑:
brew install
重新安装。在一些类似的问题中也提到了这一点。不走运。CC
、CXX
和CPP
环境变量,尽管我认为这不会有任何效果,因为它已经开始使用我的gcc v4.6
编译器了。https://stackoverflow.com/questions/23536893
