Greetings, I’m trying to use file cache in my app. Steps I’m doing:

- `require laminas/laminas-cache-storage-adapter-filesystem `
- adding section to my autoload/cache.global.php:

```auto
'filesystem' => [
            'name' => 'filesystem',
            'options' => [
                'cache_dir' => __DIR__. '/../../data/cache',
            ],
            'plugins' => [
                [
                    'name' => 'serializer',
                    'options' => [
                    ],
                ],
            ],
        ],

```

- in confg.php I’m including ConfigProvider:

```auto
$aggregator = new ConfigAggregator([
...
    \Laminas\Cache\Storage\Adapter\Filesystem\ConfigProvider::class,
...

```

and getting error:

```auto
[16-Aug-2023 09:57:49 UTC] PHP Fatal error: Uncaught Laminas\ConfigAggregator\InvalidConfigProviderException: Cannot read config from Laminas\Cache\Storage\Adapter\Filesystem\ConfigProvider - class cannot be loaded. in /var/www/vendor/laminas/laminas-config-aggregator/src/InvalidConfigProviderException.php:19

Hello and welcome to our forums! 😃

It looks like you do not use the automated configuration via the component installer; see:

> **[Installation - laminas-cache - Laminas Docs](https://docs.laminas.dev/laminas-cache/v3/installation/#installation-for-mezzio-and-laminas-mvc-application)**
>
> Caching implementation with a variety of storage options, as well as codified caching strategies for callbacks, classes, and output.

This makes no sense because it is a duplication and not needed. Check the related tutorial:

Do you use laminas-mvc or Mezzio?

I’m using Mezzio.

So I don’t understand why I’m getting error after adding `\Laminas\Cache\Storage\Adapter\Filesystem\ConfigProvider::class` to ConfigAggregator  
but before that I already used `\Laminas\Cache\Storage\Adapter\Redis\ConfigProvider::class` and did’t get any errors.

The name of the class looks good.  
Please recheck that the folder with `laminas/laminas-cache-storage-adapter-filesystem` is present in the `vendor` directory of your application.

Seems the problem was with the composer. Thanks.
