Issue installing with laravel versions

[kamy01]

Step 1 create project with laravel:
composer create-project laravel/laravel ProjectName

Step 2 run:
composer require --dev primitive/openapi-initializer

Result:

Using version ^1.4 for primitive/openapi-initializer
./composer.json has been updated
Running composer update primitive/openapi-initializer
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

    - Root composer.json requires primitive/openapi-initializer ^1.4 -> satisfiable by primitive/openapi-initializer[1.4.0].

You can also try re-running composer require with an explicit version constraint, e.g. "composer require primitive/openapi-initializer:*" to figure out if any version is installable, or "composer require primitive/openapi-initializer:^2.1" if you know which you need.

Installation failed, reverting ./composer.json to its original content.

I tried to change the laravel version but I get into other errors and couldn't solve them.
