    I am learning how to use ruby from the book, 'beginning ruby, novice to
    pro...' The chapter on using ruby with sql requires that I install
    sqlite3-ruby.

    Using sudo gem install sqlite3-ruby, I got the following--

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

    /usr/bin/ruby1.8 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:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/usr/bin/ruby1.8
    --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 /var/lib/gems/1.8/gems/sqlite3-1.3.3
    for inspection.
    Results logged to
    /var/lib/gems/1.8/gems/sqlite3-1.3.3/ext/sqlite3/gem_make.out

    going into irb,

    require 'rubygems'
    => true
    require 'sqlite3'
    no such file to load -- sqlite3 (LoadError)

    What went wrong?

    *my pc is on ubuntu 11.04. I checked synaptic package manager and see
    that sqlite3 is installed.

    You need libsqlite3-dev, which will provide sqlite3.h.

    Thanks for that quick reply.

    I looked up and installed libsqlite3-dev in synaptic package manager.
    Running irb...

    require 'sqlite3'
    =>
    LoadError: no such file to load -- sqlite3
    from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in
    `gem_original_require'
    from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require'
    from (irb):2
    from /usr/lib/ruby/1.8/rubygems.rb:123

    Unfortunately, you'll have to build the gem again, since gem and apt are
    separate package systems. Try this again:

    gem install sqlite3

    running--

    gem install sqlite3

    I got the following message--

    ERROR: While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions into the /var/lib/gems/1.8
    directory.

    so I tried--

    sudo gem install sqlite3

    and got the following--

    Building native extensions. This could take a while...
    Successfully installed sqlite3-1.3.3
    1 gem installed

    found this on google-- http://goo.gl/2zcza gave it a try and got these--

    #######################################################

    Hello! The sqlite3-ruby gem has changed it's name to just sqlite3.
    Rather than
    installing `sqlite3-ruby`, you should install `sqlite3`. Please update
    your
    dependencies accordingly.

    Thanks from the Ruby sqlite3 team!

    <3 <3 <3 <3

    going into irb--

    Yeah, that's what I meant :)

    So, does your original code work now?

    irb--

    require 'rubygems'
    => true
    require 'sqlite3'
    => true

    I think everything works now. Thank you for your help--I appreciate it!
