    The main reason why you can’t find the .env file is because it’s added to the .gitignore file. After installing the composer packages, try running:

    composer require maatwebsite/excel:^3.0.1
    Please make sure to use the compatable version of the Excel package based on your Laravel version.

    As, you’re getting fatal error for the command:

    php artisan key:generate

    Then, most probably you might forgot the create an .env file. Just copy the .env.example file and change the file name and its contents. Then run the command again.

    N.B.: You should install the dependencies with composer before key generation.

    You say you have PHP 8.1 and your project has Laravel 7 and dependencies from around that time.

    It’s very possible that a lot of your dependencies are simply not compatible with your current PHP version.

    You should upgrade gradually, following the upgrade guides in order.

    According to wikipedia1, Laravel 8 should be compatible with 8.1. If you want to install dependencies regardless of compatibility, append the --ignore-platform-reqs to your composer commands. For example:

    composer update --ignore-platform-reqs
