ruby-on-rails – 设置Ruby on Rails时出错

Following this guide,我正在尝试使用亚马逊的EC2设置Ruby on Rails.对于我的实例,我选择了“基本的32位Amazon Linux AMI 2010.11.1 Beta”.我安装了ruby,sqlite和rubygems.我在链接指南的步骤3.3中运行以下命令

bundle install

结果如下.我确定我错过了一些东西,但我很茫然.有什么建议？

Installing sqlite3 (1.3.3) with native extensions /usr/lib/ruby/site_ruby/1.8/rubygems    /installer.rb:529:in `build_extensions': ERROR: Failed to build gem native extension (Gem::Installer::ExtensionBuildError)

/usr/bin/ruby extconf.rb 
mkmf.rb can't find header files for ruby at /usr/lib/ruby/ruby.h

Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/sqlite3-1.3.3 for inspection.

编辑：按照下面的建议安装ruby-devel,我现在除了原始错误之外还得到此错误.

Installing sqlite3 (1.3.3) with native extensions /usr/lib/ruby/site_ruby/1.8/rubygems/installer.rb:529:in `build_extensions': 
ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

    /usr/bin/ruby extconf.rb 
checking for sqlite3.h... no
sqlite3.h is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite3-devel' and check your shared library search path (the
location where your sqlite3 shared library is located).

但是当我试着奔跑的时候

yum install sqlite-devel

我被告知：

Package sqlite-devel-3.6.20-1.6.amzn1.i386 already installed and latest version
Nothing to do
