我正在尝试在Mavericks上安装以下gem版本

  • libv8(3.16.14.3)
  • therubyracer(0.12.1)

显然therubyracer gem取决于libv8。

所以我安装libv8

gem install libv8 -- --with-system-v8

这是我的理解,这安装了gem,但使用我的本地系统安装的V8库,而不是...随gem版本?

无法安装therubyracer gem。我不太清楚这gem是做什么的,只是它是我想要的一个rails项目的依赖bundle install

它给了我以下错误:

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

Gem files will remain installed in /Users/jeeves.butler/.rvm/gems/ruby-1.9.2-p290/gems/therubyracer-0.12.1 for inspection.
Results logged to /Users/jeeves.butler/.rvm/gems/ruby-1.9.2-p290/extensions/x86_64-darwin-13/1.9.1/therubyracer-0.12.1/gem_make.out

从我可以收集的内容中,我选择libv8使用本地V8库进行安装,而不是使用随附的内容libv8,但现在无法找到本地安装。

以下代码:

gem uninstall libv8
gem install therubyracer -v '0.11.3'
gem install libv8 -v '3.11.8.13' -- --with-system-v8

对于那些在OS X El Capitan中遇到这个问题的人来说,这个解决方案:

brew tap homebrew/versions
brew install v8-315

gem install libv8 -v '3.16.14.13' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8-315

bundle install

我之前也跑过brew install gcc,但我不确定这是否有必要。
