skip to Main Content

I have a docker container with php 8.0.0-dev and composer. I want to create a Laravel application to test the new PHP but I have some errors.

When I try to create a new laravel project with the command:

composer create-project laravel/laravel test

The error I get is that I don’t have the required PHP even though php 8.0.0 is greater than php 7.x.

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laravel/framework v5.6.9 requires php ^7.1.3 -> your PHP version (8.0.0-dev) does not satisfy that requirement.
    - laravel/framework v5.6.8 requires php ^7.1.3 -> your PHP version (8.0.0-dev) does not satisfy that requirement.
    ...
    ...

Can I skip the php version check somehow?

I have tried with

--prefer-dist

and

--ignore-platform-reqs

but i obtain this error:

 Problem 1
    - Conclusion: don't install laravel/laravel v7.25.0|remove laravel/laravel v7.25.0
    - Installation request for laravel/laravel v7.25.0 -> satisfiable by laravel/laravel[v7.25.0].

Any idea?

Thanks!!!

  1. Laravel supports PHP 8.0 right now, however still some packages are not updated. It affects also some of the PHP extensions:
    https://blog.remirepo.net/pages/PECL-extensions-RPM-status

    First, make sure you’re at the latest version of Laravel 6, 7 or 8 to
    get PHP 8 support. Then make sure you’re on the very latest version of
    any first-party package from Laravel like Passport, Cashier, Dusk,
    etc.

    There are also a couple of commonly used dependencies you’ll need to
    update in your composer.json file:

    PHP to php:^8.0    
    Faker to fakerphp/faker:^1.9.1    
    PHPUnit to phpunit/phpunit:^9.3
    

    Finally, run composer update to update other packages. Make sure to
    test your application before updating production. That’s it! Enjoy PHP
    8!

  2. You are trying to install laravel 5.
    For PHP 8 you need at least laravel 6,7 or 8
    I prefer laravel 8 (last one)

    If you use docker according to laravel 8 documentation you can create project with command:

    curl -s https://laravel.build/example-app | bash
