使用本机扩展构建gem(Gem :: Installer :: ExtensionBuildError)

Question

我有以下配置:

• uname -a: Linux 2.6.24.2 i686 GNU/Linux(Ubuntu)
• ruby -v: ruby 1.9.0(2007-12-25修订版14709)[i486-linux]
• rails -v: Rails 3.0.0.beta3
• gem -v:1.3.5
• rake --version: rake,版本0.8.7
• make -v: GNU Make 3.81
• 宝石环境:
  • RUBYGEMS版本:1.3.5
  • RUBY版本:1.9.0(2007-12-25补丁级别0)[i486-linux]
  • 安装目录:/usr/lib/ruby1.9/gems/1.9.0
  • RUBY EXECUTABLE:/usr/bin/ruby1.9
  • 可执行的目录:/ usr/bin
  • RUBYGEMS PLATFORMS:
  • 红宝石
  • x86架构的Linux
  • 创业板路径:
    • /usr/lib/ruby1.9/gems/1.9.0
    • /root/.gem/ruby/1.9.0
  • 创业板配置:
    • :update_sources => true
    • :verbose => true
    • :benchmark => false
    • :backtrace => false
    • :bulk_threshold => 1000
  • 远程来源:
    • http://gems.rubyforge.org/

当我尝试这个简单的命令:

gem install nokogiri

这是我得到的:

# gem install nokogiri
Building native extensions.  This could take a while...
ERROR:  Error installing nokogiri:
        ERROR: Failed to build gem native extension.

"gem_make.out"文件包含与上述完全相同的信息.

如果我尝试另一个宝石:

gem install gherkin

这是我得到的:

u# gem install gherkin

ERROR:  Error installing gherkin:
        ERROR: Failed to build gem native extension.

事实上,每当我尝试安装具有原生扩展名的gem时,我都会遇到相同类型的错误.

这会给任何人敲响声吗？
