首先，我将从我在MAC上这一事实开始。
我已经将cakeDC注释插件git克隆到我的应用程序插件目录中。在尝试执行给定的命令来设置这个插件的数据库表时，我收到了这个错误：
sudo Console/cake scheme create --plugin Comments --name app

Error: Shell class SchemeShell could not be found.
#0 /Users/bellis/workspace/intranet/lib/Cake/Console/ShellDispatcher.php(167): ShellDispatcher->_getShell('scheme')

#2 /Users/bellis/workspace/intranet/app/Console/cake.php(33): ShellDispatcher::run(Array)

为什么这个命令试图在我的MAC安装上使用.dll文件（仅限Windows）。我这里缺了什么吗？我们非常感谢您的帮助。
Error: Shell class SchemeShell could not be found.

所以我只花了大约15分钟的时间在堆栈痕迹中搜寻，试图弄清楚这一点。我在任何地方都找不到SchemeShell.php文件，但我注意到Cake/Console/Command目录中有一个SchemaShell.php。环顾四周一段时间后，我更好地查看了正在输入的控制台命令。
c:'wamp'www'app>Console'cake scheme create DbAcl
这时，我从手掌到前额，花了一会儿时间自嘲。我试图创建一个方案，但告诉Cake让我创建一个方案，这显然对我来说不太好。
