Question

我正在尝试在RHEL 6上安装Ruby on Rails 3.我已经安装了sqlite和sqlite-devel（在RHEL6上是sqlite3）。如您所见，sqlite3.h确实存在于需要的位置。由于某种原因，'gem install sqlite3-ruby'仍然无效。

SQLite3的：

[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
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 ***
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-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/usr/bin/ruby
    --with-sqlite3-dir
    --without-sqlite3-dir
    --with-sqlite3-include
    --without-sqlite3-include=${sqlite3-dir}/include
    --with-sqlite3-lib
    --without-sqlite3-lib=${sqlite3-dir}/lib


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

PS：创建'rhel6'标签肯定会很好，但我没有足够的声誉。

Answer 1

事实证明你必须为'gem install sqlite3-ruby'安装gcc才能工作。它永远不会明确地告诉你找不到gcc（即使日志文件也没有提到它）。

Answer 2

我已经安装了sqlite和 sqlite-devel（这是sqlite3） RHEL6）

那不是真的。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，请始终使用此命令来查找它：

# 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。
