I have the same problem

[cviebrock]

Did you publish the configuration file?

Did you publish the configuration file?

I got the error on installing the package by composer and because of the error the package won't be installed

[cviebrock]

Which version of Laravel are you using? I just tried a fresh project, and I didn't get the same error as you.

> composer create-project laravel/laravel laravel8
...
> cd laravel8
> composer require cviebrock/laravel-elasticsearch

Can you try the above and see what you get?

Maybe it's a XAMPP issue (I don't have a Windows machine handy for testing).

Hi there. It's happening to me too.
I am using latest Laravel 8.x, on a Linux machine.

Error is exactly the same.
I even tried to create the config/elasticsearch.php file BEFORE running composer, and got exactly the same error...

Do I have to install previously some other composer package related to Elasticsearch?

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

The way i fixed it is to create a config/elasticsearch.php AND deleting the files in bootstrap/cache
