无法安装 sqlite3-ruby gem

Question

我已经安装了 xcode 3.0。我需要安装 sqlite3-ruby gem（用于 rhosync）。

当我跑步时：

sudo gem install -l sqlite3-ruby

我收到以下错误：

Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3-ruby:
 ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:

 --without-sqlite3-include=${sqlite3-dir}/include
 --with-sqlite3-lib
 --without-sqlite3-lib=${sqlite3-dir}/lib
 --with-sqlite3lib
 --without-sqlite3lib


Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/sqlite3-ruby-1.3.1 for inspection.

我检查了很多链接（在 Stack Overflow 和其他网站上），但似乎没有任何效果。

有些人建议从 Mac OS X Disk 2 安装 Ruby Headers。但我没有那个光盘。我已经安装了 XCode 3.0 SDK。

我该怎么办？

Answer 1

我从http://macports.org 安装了 MacPorts，然后运行

sudo port install sqlite3

sqlite3-ruby 安装成功后。
