no such file to load -- sqlite3/sqlite3_native

Question

I am having trouble trying to run the following ruby script on OSX (Leopard).

    require 'sqlite3'
    database = SQLite3::Database.new( "new.database" )

    database.execute( "create table sample_table (id INTEGER PRIMARY KEY, sample_text TEXT, sample_number NUMERIC);" )

    database.execute( "insert into sample_table (sample_text,sample_number) values ('Sample Text1', 123)")
    database.execute( "insert into sample_table (sample_text,sample_number) values ('Sample Text2', 456)")

    rows = database.execute( "select * from sample_table" )

    p rows

but I get the following error:

/Users/Ted/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': no such file to load -- sqlite3/sqlite3_native (LoadError)
    from /Users/Ted/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'

    from <internal:lib/rubygems/custom_require>:29:in `require'
    from sequelsample.rb:1:in `<main>'

How can I fix this issue? I have installed the following gems with the commands using ruby 1.9.2p180 (2011-02-18 revision 30909) [i386-darwin9.8.0]:

sudo gem install sqlite3-ruby -- --with-sqlite3-dir=/sw
sudo gem install sqlite3 -- --with-sqlite3-dir=/sw

sqlite3 (1.3.4)
sqlite3-ruby (1.3.3)

Answer 1

Fixed it with this commands:

  gem uninstall sqlite3
  gem uninstall sqlite3-ruby
  sudo gem install sqlite3 -- --with-sqlite3-dir=/sw
