ci 怎么配置 sqlite 数据库

lcpmaxview

请教高手，在ci框架中怎么配置 sqlite 数据库
刚下载的ci版本： CodeIgniter_2.1.0
sqlite 数据库版本： 3.7.8

数据库放在项目根目录下的database 目录下面
ci/database/db.sdb


目前的配置
$active_group = 'default';
$active_record = TRUE;

$db['default']['hostname'] = 'localhost';
$db['default']['username'] = '';
$db['default']['password'] = '';
$db['default']['database'] = realpath('./database/db.sdb');
$db['default']['dbdriver'] = 'sqlite';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

配置完后，运行报
( ! ) Fatal error: [] operator not supported for strings in E:\wamp\www\ci\system\database\DB_driver.php on line 1183

用PDO 连接sqlite3,

要在网上找一个PDO的插件好像才可以.CI2自带的不行.
