我正在尝试在 RHEL 6 上安装 Ruby on Rails 3。我已经“yum install”sqlite 和 sqlite-devel（这是 RHEL6 上的 sqlite3）。如您所见， sqlite3.h 确实存在于它需要的位置。由于某种原因，“gem install sqlite3-ruby”仍然不起作用。

SQLite3：

[root@rhel6base gems]# yum list sqlite-devel
Installed Packages
sqlite-devel.x86_64            3.6.20-1.el6            @local
Available Packages
sqlite-devel.i686              3.6.20-1.el6            local 

[root@rhel6base gems]# ls -l /usr/include/sqlite3.h
-rw-r--r--. 1 root root 268966 Nov 24  2009 /usr/include/sqlite3.h

宝石安装：

[root@rhel6base gems]# gem install sqlite3-ruby
Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3-ruby:
    ERROR: Failed to build gem native extension.

        /usr/bin/ruby extconf.rb

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).

Gem files will remain installed in /usr/lib64/ruby/gems/1.8/gems/sqlite3-1.3.3 for inspection.

PS：创建一个'rhel6'标签肯定很好，但我没有足够的声誉。

事实证明，您必须安装 gcc 才能使“gem install sqlite3-ruby”工作。它永远不会明确告诉您找不到 gcc（即使日志文件也没有提及）。

我有'yum install' sqlite 和 sqlite-devel（在 RHEL6 上是 sqlite3）

这不是真的。从我的 RHEL6 服务器安装：

# yum search sqlite
...
sqlite.i686 : Library that implements an embeddable SQL database engine
sqlite-devel.i686 : Development tools for the sqlite3 embeddable SQL database engine
...

您缺少 sqlite3.h 文件。如果您需要一个应该在 RHEL6 存储库中的文件，请始终使用以下命令来查找它：

# yum provides /usr/include/sqlite3.h
sqlite-devel-3.6.20-1.el6.i686 : Development tools for the sqlite3 embeddable SQL database engine
Repo        : rhel-i386-server-6.0.z
Matched from:
Filename    : /usr/include/sqlite3.h

因此安装 sqlite-devel包，您将能够成功编译。祝你好运。
