gii不与yiiexcel合作

我正在使用Yii，并且有一个插件YiiExcel。当这个插件加载时，Gii不起作用。我的index.php

//do not run app before register YiiExcel autoload
$app = Yii::createWebApplication($config);
Yii::import('ext.yiiexcel.YiiExcel', true);
Yii::registerAutoloader(array('YiiExcel', 'autoload'), true);
// Optional:
//  As we always try to run the autoloader before anything else, we can use it to do a few
//      simple checks and initialisations
PHPExcel_Shared_ZipStreamWrapper::register();
if (ini_get('mbstring.func_overload') & 2) {
    throw new Exception('Multibyte function overloading in PHP must be disabled for string functions (2).');
}
PHPExcel_Shared_String::buildCharacterSets();
//Now you can run application
$app->run();

当我尝试生成一个文件时，我会得到
