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

1. First download the REDIS to your system (if you haven't already installed it).

2. Go to the folder where you have downloaded the redis and run this command:

   cd your-redis-folder-name
   make
   

3. Go to your project directory and install composer:

   composer require predis/predis

4. Go to your .env file and add Queue driver:

   QUEUE_DRIVER=redis
   

5. use Mail::queue() to send mail via queue. See Doc.

6. And in your terminal run:

   php artisan queue:listen 
   

   to send.

Write in console in project folder:

composer require predis/predis

And thats all.

You need to add predis/predis into composer.json for your project. Reference: https://laravel.com/docs/5.2/redis#introduction
