Are you using horizon with Laravel 5.5?

[terryzwt]

Laravel Framework 5.4.32

[devcircus]

See #32. There are no plans to support < 5.5.

[terryzwt]

If horizon only support laravel >= 5.5, why not put the dependency in the composer.josn file?

[themsaid]

Check https://github.com/laravel/horizon/blob/master/composer.json

@terryzwt add this line to your config/app.php in laravel 5.4 project

You need to add a record in providers array.
Laravel\Horizon\HorizonServiceProvider::class,

After this run php artisan vendor:publish --provider="Laravel\Horizon\HorizonServiceProvider"
Then run php artisan horizon.

It should be up and running.
