我已将引导扩展添加到我的 yii webapp 并按照安装指南中的说明进行安装。扩展文件夹中的所有文件夹都是 rwrwrw 但我收到上面写的错误。可能是什么原因？我已经从 yii::Import 中转储了路径，并且该路径是正确的。
谢谢！
用代码编辑
这是我的配置：
Yii::setPathOfAlias('bootstrap', dirname(__FILE__).'/../extensions/bootstrap');
//Yii::setPathOfAlias('bootstrap', '/Users/gerritlober/Sites/yii/webapp/protected/extensions/bootstrap');
// This is the main Web application configuration. Any writable
// CWebApplication properties can be configured here.
