nokogiri - 错误:无法构建gem原生扩展

Question

我更新了Lion的开发者版本,发现我再也无法启动rails应用程序了.每当我尝试时sudo bundle install,我都会收到以下错误:

Installing nokogiri (1.4.4) with native extensions /Library/Ruby/Site/1.8/rubygems/installer.rb:551:in `build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

Answer 1

尝试安装"libxslt1-dev"和"libxml2-dev"软件包.

Answer 2

谢谢大家 - 当我更新到Lion时,我需要安装x代码4.1才能在后台获取正确的文件,以便捆绑程序安装所有正确的软件包.现在一切都很好吃!
