when i do php artisan tinker as described on Repo's README.md file i got this error:

[Symfony\Component\Console\Exception\CommandNotFoundException]
  Command "tinker" is not defined.

i tried this on an empty project from scratch and tinker is working - not on my current project

Tell me if more informations are needed

Are you using Lumen? Have you registered the service provider?

[PaoloFalomo]

I just fixed this by adding

protected $commands = [
        TinkerCommand::class
    ];

in my app/Console/Kernel.php file.

Note Remember even to add the use Laravel\Tinker\Console\TinkerCommand;

//app/Console/Kernel.php file
...
use Laravel\Tinker\Console\TinkerCommand;
class Kernel extends ConsoleKernel{
...

[GrahamCampbell]

That's not the correct fix. Please register the service provider:

$app->register(Laravel\Tinker\TinkerServiceProvider::class);

[GrahamCampbell]

Otherwise tinker will not work correctly.

[PaoloFalomo]

@GrahamCampbell yep! i di registered the service provider but it didn't worked.

Did you run php artisan config:cache?

[PaoloFalomo]

php artisan config:cache solved the problem!! This should be added on readme.md file - i lost too much time for this :(

thank you @GrahamCampbell !!
