关于yii中gii的配置问题，大家帮我看看，谢谢了！ [ 新手入门 ]

首先，我的yii中blog配置文件目录是 D:\wamp\www\yii\demos\blog\protected\config\main.php

然后，我的main.php文件中配置如下

<?php
// uncomment the following to define a path alias
// Yii::setPathOfAlias('local','path/to/local-folder');

// This is the main Web application configuration. Any writable
// CWebApplication properties can be configured here.
return array(
    'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
	'name'=>'Yii Blog Demo',

	// preloading 'log' component
	'preload'=>array('log'),

	// autoloading model and component classes
	'import'=>array(
		'application.models.*',
		'application.components.*',
	),

    'modules'=>array(
        'gii'=>array(
            'class'=>'system.gii.GiiModule',
            'password'=>'123456',
        ),
    ),

	'defaultController'=>'post',

	// application components
	'components'=>array(
		'user'=>array(
			// enable cookie-based authentication
			'allowAutoLogin'=>true,
		),
		'db'=>array(
			'connectionString' => 'sqlite:protected/data/blog.db',
			'tablePrefix' => 'tbl_',
		),
		// uncomment the following to use a MySQL database
		
		'db'=>array(
			'connectionString' => 'mysql:host=localhost;dbname=blog',
			'emulatePrepare' => true,
			'username' => 'root',
			'password' => '',
			'charset' => 'utf8',
			'tablePrefix' => 'tbl_',
		),
		
		'errorHandler'=>array(
			// use 'site/error' action to display errors
            'errorAction'=>'site/error',
        ),
        'urlManager'=>array(
        	'urlFormat'=>'path',
        	'rules'=>array(
        		'post/<id:\d+>/<title:.*?>'=>'post/view',
        		'posts/<tag:.*?>'=>'post/index',
        		'<controller:\w+>/<action:\w+>'=>'<controller>/<action>',
        	),
        ),
		'log'=>array(
			'class'=>'CLogRouter',
			'routes'=>array(
				array(
					'class'=>'CFileLogRoute',
					'levels'=>'error, warning',
				),
				// uncomment the following to show log messages on web pages
				/*
				array(
					'class'=>'CWebLogRoute',
				),
				*/
			),
		),
	),

	// application-level parameters that can be accessed
	// using Yii::app()->params['paramName']
	'params'=>require(dirname(__FILE__).'/params.php'),
);

最后输入http://localhost/yii/demos/blog/index.php?r=gii以后，页面还是停留在home/about/contact/login主页面上， 为什么它没有出现让我输入gii密码的页面呢？ 还有一点是我的yii requirements中有APC、MEMCACHE、和PDO Postgresql扩展模块未通过 帮忙求解！谢谢！
