Command is not defined exception

问题

I created a command with Artisan

$ php artisan command:make NeighborhoodCommand

This created the file app/commands/NeighborhoodCommand.php

Snippet of the code. I modified the name value and filled in the fire() function

<?php

use Illuminate\Console\Command;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Input\InputArgument;

class NeighborhoodCommand extends Command {

    protected $name = 'neighborhood';

    public function fire()
    {
        // my code
    }
}

But then when I try to run the command with

$ php artisan neighborhood

I get this error:

[InvalidArgumentException]
Command "neighborhood" is not defined.

Laravel 5.5+

https://laravel.com/docs/5.5/artisan#registering-commands

If you'd like, you can continue manually registering your commands. But L5.5 gives you the option to lazy load them. If you are upgrading from an older version add this method to your Kernel:

/**
 * Register the commands for the application.
 *
 * @return void
 */
protected function commands()
{
    $this->load(__DIR__ . '/Commands');

    require base_path('routes/console.php');
}

Laravel 5

http://laravel.com/docs/5.4/artisan#registering-commands

Edit your app/Console/Kernel.php file and add your command to the $commands array:

protected $commands = [
    Commands\NeighborhoodCommand::class,
];

Laravel 4

http://laravel.com/docs/4.2/commands#registering-commands

Add this line to app/start/artisan.php:

Artisan::add(new NeighborhoodCommand);

By changing signature in your command class to your commandName. change

protected $signature = 'command:name';

protected $signature = 'NeighborhoodCommand';

Now try to run

$ php artisan command:make NeighborhoodCommand

It works for me.
