I'm getting error “Class 'Predis\Client' not found” in Laravel 5.2

Question

I want to using Redis in laravel 5.2 however, I\'m getting error such a Class \'Predis\\Client\' not found, How I can solve it.

Answer 1

Btw, if you are using laravel workers, with ubuntu supervisor and this error will not dissappear even after you did

composer require predis/predis

Then remember kids, that supervisor caches all your php code, once you boot it. So installing predis after you booted supervisor workers (https://laravel.com/docs/5.6/queues#supervisor-configuration), will not make a difference, until you do

sudo supervisorctl stop laravel-worker:*

and then start it again

sudo supervisorctl start laravel-worker:*

I've been stuck on this for an hour or two, on 3 projects in the last year.
