Php 无法声明类'；TestCommandRun'；，因为该名称已在使用中

我使用的是

laravel 5.4

我正在使用

php artisan list

，但出现以下错误：

C:\Users\admin\Desktop\Coding Projects\demo_laravel>php artisan list
PHP Fatal error:  Cannot declare class TestCommandRun, because the name is already in use in C:\Users\admin\Desktop\Coding Projects\demo_laravel\app\Console\Commands\TestCommandRun.php on line 109

In TestCommandRun.php line 109:

  Cannot declare class TestCommandRun, because the name is already in use

我的命令具有正确的名称：

class TestCommandRun extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'TestCommandRun:run';

在my Kernel.php中，我已将其添加到

$commands

部分：

protected $commands = [
    '\App\Console\Commands\TestCommandRun',        
];

有什么建议可以解释为什么会出现上述错误消息吗？

看起来您有两个具有相同类名的命令

TestCommandRun

。因此，您需要删除一个

另外，在这之后运行

composer du

命令也是一个好主意。

谢谢您的回复！作曲家杜到底做了什么？@mrquad很高兴这有帮助。这是

composer dump autoload

的快捷方式。你可能想看看这个。
