问题描述

我无法在 Yosemite 10.10 上安装 therubyracer gem.

这是日志:

解决方案

git clone https://github.com/cowboyd/libv8.git光盘 libv8捆绑安装bundle exec rake clean build 二进制文件gem install pkg/libv8-3.16.14.3-x86_64-darwin-12.gem #注意libv8版本可能会改变，所以在pkg/中的文件中使用tab，还记得使用指定版本的那个

然后只需捆绑您的项目 gems

这是它在 10.10 (ruby 2.1.2) 上对我有用的唯一方法

I don't manage to install therubyracer gem on Yosemite 10.10.

Gem files will remain installed in /usr/local/var/rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/therubyracer-0.12.1 for inspection.

解决方案

git clone https://github.com/cowboyd/libv8.git
cd libv8
bundle install
bundle exec rake clean build binary
gem install pkg/libv8-3.16.14.3-x86_64-darwin-12.gem #note that libv8 version may change, so tab through files in pkg/, also remember to use the one with version specified

then just bundle your project gems

this is the only way it worked for me on 10.10 (ruby 2.1.2)
