Linux Mint 16 + Ruby + SQLite3の導入

Ruby + SQlite3の勉強をすべく、gemでsqlite3-rubyを導入しようとしてつまづきました。

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

Gem files will remain installed in /var/lib/gems/1.9.1/gems/sqlite3-1.3.9 for inspection.

調べたところ、先にruby-devパッケージを導入する必要があるらしい。

$ sudo apt-get install ruby-dev

この後にもう一度試すと、、

$ sudo gem install sqlite3-ruby

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!
