我最近将 OSX 升级到 Mountain Lion (10.8) 和 Xcode (4.4)，但在尝试让我的 rails 环境正常工作时遇到了问题。我开始运行并在安装库bundle install时遇到错误。libv8以下是完整错误的粘贴。我四处搜索并寻找类似的问题，但到目前为止我在 stackoverflow 上发现的内容并未适用于我的问题。以下是我迄今为止尝试过的几件事无济于事：
- 安装 Xcode 命令行工具
- 安装 MySQL
- 安装 X11
- 通过 gemfile 安装不同版本的 libv8
现在我的问题似乎超出了我的红宝石技能。如果有人对我可以尝试的方法有什么想法或遇到类似问题，我希望您能提供帮助。谢谢！
这是我的 gemfile 的样子：
source 'https://rubygems.org'
gem 'rails', '3.2.6'
gem 'bundler'
gem 'rake'
gem 'sqlite3'
gem 'haml'
gem 'nokogiri'
gem 'whenever'
gem 'mysql'
gem 'mysql2'
gem 'jquery-rails'
gem 'capistrano'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
这是尝试安装 gems 时的错误日志：
sudo bundle install
