我在命令行下用“yiic YiiDemo E:\webroot\Demo\”创建时，出现下面的描述：
[font="Book Antiqua"]Yii command runner (based on Yii v1.1.2)
Usage: E:\Yii\framework\yiic <command-name> [parameters…]
The following commands are available:
-
message
-
shell
-
webapp
To see individual command help, use the following:
E:\Yii\framework\yiic help <command-name>[/font]
想请问下，这是什么问题呢？
