Your requirements could not be resolved to an installable set of packages

Versions:

• ide-helper Version: ^2.12.0
• Laravel Version: 6.20.44
• PHP Version: 7.4.29

Question:

When i run composer require --dev barryvdh/laravel-ide-helper, i get a composer error, but it isn't clear to me what's the problem.
It says ... require illuminate/console ^8 || ^9 -> found illuminate/console[v8.0.0 ... so i don't understand what is going wrong.
Here's the log:

PS C:\projects\projectX> composer require --dev barryvdh/laravel-ide-helper
./composer.json has been updated
Running composer update barryvdh/laravel-ide-helper
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - barryvdh/laravel-ide-helper[v2.12.0, ..., 2.12.x-dev] require illuminate/console ^8 || ^9 -> found illuminate/console[v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev] but these were not loaded, likely because it conflicts with another require.   
    - Root composer.json requires barryvdh/laravel-ide-helper ^2.12 -> satisfiable by barryvdh/laravel-ide-helper[v2.12.0, ..., 2.12.x-dev].     

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

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

And here's the full composer.json:

Laravel 6 hasn't been supported for some time, see #1114

I guess the docs/readme could be made clearer about this.

Thank you, i didn't know that!
Since this project won't be updated to Laravel 7+, I simply installed version ide helper v2.8 and it is now working.
I'm closing the issue.

I can install with this command
composer require --dev barryvdh/laravel-ide-helper --update-with-all-dependencies
