composer installation problem in laravel 9

[urshar]

I have installed laravel 9 with livewire and tailwind. I tried to install the last version of laravel-excel. I get following message:

Problem 1
    - phpoffice/phpspreadsheet[1.18.0, ..., 1.21.0] require psr/simple-cache ^1.0 -> found psr/simple-cache[1.0.0, 1.0.1] but the package is fixed to 3.0.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - maatwebsite/excel 3.1.36 requires phpoffice/phpspreadsheet ^1.18 -> satisfiable by phpoffice/phpspreadsheet[1.18.0, 1.19.0, 1.20.0, 1.21.0].
    - Root composer.json requires maatwebsite/excel 3.1.36 -> satisfiable by maatwebsite/excel[3.1.36].

Laravel is a fresh installation and have no additional apps installed as written. Any Idea why I got this messages

You have to set simple cache to 1.0 in your composer. Phpspreadsheet doesn't support newer version of that package

Problem 1
    - maatwebsite/excel[3.1.36, ..., 3.1.x-dev] require phpoffice/phpspreadsheet ^1.18 -> satisfiable by phpoffice/phpspreadsheet[1.18.0, 1.19.0, 1.20.0, 1.21.0].
    - maatwebsite/excel[3.1.0, ..., 3.1.25] require php ^7.0 -> your php version (8.1.2) does not satisfy that requirement.
    - maatwebsite/excel[3.1.26, ..., 3.1.35] require illuminate/support 5.8.*|^6.0|^7.0|^8.0 -> found illuminate/support[v5.8.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev] but these were not loaded, likely because it conflicts with another require.
    - phpoffice/phpspreadsheet[1.18.0, ..., 1.21.0] require psr/simple-cache ^1.0 -> found psr/simple-cache[1.0.0, 1.0.1] but the package is fixed to 3.0.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - Root composer.json requires maatwebsite/excel ^3.1 -> satisfiable by maatwebsite/excel[3.1.0, ..., 3.1.x-dev].

How about this kind of error Sir?
Error from fresh Laravel 9 using PHP 8.1.2 I received another set of errors when using PHP 8.0.15

You have the same error. Please see the updated installation instructions for Laravel 9: https://docs.laravel-excel.com/3.1/getting-started/installation.html

Yes Sir, I read that part of the documentation assuming that there has a new installation guide. I am using fresh Laravel. I read the other user's post, about the error, He didn't encounter the errors when upgrading from L8 to L9.
