在 CakePHP v2.6.4 中运行：./cake hello，报错：Error Shell class HelloShell could not be found. 的分析解决

1、参考网址：https://book.cakephp.org/2/en/console-and-shells.html ，创建一个简单的 Hello world shell。 在应用程序的 Console/Command 目录中，创建 HelloShell.php。

<?php
/**
 * Created by PhpStorm.
 * User: Qiang Wang
 * Date: 2020/08/18
 * Time: 15:04
 */

class HelloShell extends AppShell {
    public function main() {
        $this->out('Hello world.');
    }
}

2、进入目录：E:\wwwroot\creditshop\app\Console，执行：./cake hello，报错：Error Shell class HelloShell could not be found. 如图1

图1

PS E:\wwwroot\creditshop\app\Console> ./cake hello

Error: Shell class HelloShell could not be found.
#0 E:\wwwroot\creditshop\lib\Cake\Console\ShellDispatcher.php(200): ShellDispatcher->_getShell('hello')
#1 E:\wwwroot\creditshop\lib\Cake\Console\ShellDispatcher.php(66): ShellDispatcher->dispatch()
#2 E:\wwwroot\creditshop\app\Console\cake.php(47): ShellDispatcher::run(Array)
#3 {main}
