LogicException：请确保已安装并启用 PHP Redis 扩展

UMA*_*ALI 27 redis laravel predis laravel-events laravel-7

Laravel 版本：7.5.0 PHP 版本：7.2 数据库驱动和版本：Redis

一切正常，但突然出现此错误，我将 phpredis 更改为 predis 但错误相同。

重现步骤：我正在调用事件函数 event(new ChatsEvent($data));

LogicException: Please make sure the PHP Redis extension is installed and enabled. in /home/user/public_html/vendor/laravel/framework/src/Illuminate/Redis/Connectors/PhpRedisConnector.php:76

如果您使用安装Redis composer require predis/predis，则需要将此行添加到.env文件中：

REDIS_CLIENT=predis

An additional way您可以在config/database.php文件中更改这一行：

从：

'client' => env('REDIS_CLIENT', 'phpredis'),

到：

'client' => env('REDIS_CLIENT', 'predis'),

或者您可以将 REDIS_CLIENT=predis 添加到您的 .env 文件中 (3认同)

缺少 PHP redis 扩展。

有两种方式：

安装 php redis 扩展（回答/sf/answers/4292773831/）
更改驱动程序predis（REDIS_CLIENT在.ENV），并安装predis作曲家包（composer require predis/predis）。

但是predis慢一点phpredis。

PS：（对于方式 1）：安装 phpredis 扩展后，您需要将其添加composer.json到require部分以"ext-redis": "*"进行适当的部署。请参阅Composer 平台要求。

如果您在 Windows 中，请使用此composer require predis/predis命令添加 predis 的依赖项。然后像这样配置你的 .env 文件

BROADCAST_DRIVER=log
CACHE_DRIVER=file
QUEUE_CONNECTION=redis
SESSION_DRIVER=file
SESSION_LIFETIME=120

REDIS_CLIENT=predis
REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

我正在使用 redis 来排队我的邮件。所以我设置QUEUE_CONNECTION=redis和REDIS_CLIENT=predis。当你在本地开发时，这很好用。在生产中它相同但有点不同
