- First download the REDISto your system (if you haven't already installed it).
Go to the folder where you have downloaded the redis and run this command:
cd your-redis-folder-name makeGo to your project directory and install composer:
composer require predis/predisGo to your .env file and add Queue driver:
QUEUE_DRIVER=redis- use
Mail::queue()to send mail via queue. See Doc. And in your terminal run:
php artisan queue:listento send.

Write in console in project folder:
在项目文件夹中的控制台中写入：
composer require predis/predis
And thats all.
就这样。

You need to add predis/predisinto composer.jsonfor your project. Reference: https://laravel.com/docs/5.2/redis#introduction
你需要为你的项目添加predis/predis进去composer.json。参考：https: //laravel.com/docs/5.2/redis#introduction

we have add composer.json file "predis/predis": "~1.0" help working fine.
我们添加了 composer.json 文件 "predis/predis": "~1.0" 帮助工作正常。

Btw, if you are using laravel workers, with ubuntu supervisor and this error will not dissappear even after you did
顺便说一句，如果您使用的是 laravel 工作人员，则与 ubuntu 主管一起使用，即使您这样做，此错误也不会消失
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
然后记住孩子们，一旦你启动它，主管就会缓存你所有的 php 代码。因此，在您启动主管工作人员（https://laravel.com/docs/5.6/queues#supervisor-configuration）后安装 predis不会产生任何影响，直到您这样做
sudo supervisorctl stop laravel-worker:*
and then start it again
然后重新开始
sudo supervisorctl start laravel-worker:*
I've been stuck on this for an hour or two, on 3 projects in the last year.
去年，我在 3 个项目上被困在这个问题上一两个小时。

Running composer dumpafter installing predis/predis package might be necessary
composer dump可能需要在安装 predis/predis 包后运行

I solved the problem just including the use Predis;above class file in app folder.
我解决了这个问题，只是use Predis;在 app 文件夹中包含了上面的类文件。
If you installed predis via composer require predis/predis already.
如果您通过 composer 安装了 predis，则需要 predis/predis。
