Ruby 我能'；t为Ubuntu 10安装sqlite3 gem

我使用apt get在运行Ubuntu 10的VPS中安装sqlite3。我可以毫无问题地运行sqlite3。但是，当我尝试使用gem安装sqlite3时，出现了以下错误：

root@makserver:/# gem install sqlite3
Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3:
    ERROR: Failed to build gem native extension.

        /usr/local/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).
*** extconf.rb failed ***

Gem files will remain installed in /usr/local/lib/ruby/gems/1.9.1/gems/sqlite3-1.3.3 for inspection.

有什么建议吗？

您需要首先安装sqlite开发头，以便它可以根据这些头编译gem：

sudo apt-get install libsqlite3-dev

然后试着安装gem。

你应该更新到Ruby 1.9.2，它修复了很多问题。Ruby已经是1.9.2了，我自己编译它，它可以工作！我想知道什么是开发头，它的用途是什么？sqlite3 gem是一个Ruby C扩展，因此它必须被编译。因为它需要在编译中包含sqlite3库头，所以它需要这个包。
