Problema ao instalar o SQLite3 RubyGem no Ubuntu

Question

Estou com um problema ao tentar instalar o SQLite3 RubyGem. Veja o que estou fazendo:

$ sudo gem install --remote sqlite3-ruby

Aqui está a saída:

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 fdatasync() in -lrt... yes
checking for sqlite3.h... no
*** 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

    --with-sqlite3-lib
    --without-sqlite3-lib=${sqlite3-dir}/lib
    --with-rtlib
    --without-rtlib


Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.5 for inspection.

Esta é sua resposta:

Primeiro eu instalei o banco de dados Sqlite3:

sudo apt-get install sqlite3

Depois disso, instalamos o lib para não recebermos o erro:

sudo apt-get install libsqlite3-dev

Agora podemos instalar a gema sem o erro:

sudo gem install sqlite3-ruby

O primeiro comando (instalando o sqlite3) pode não ser necessário.
