If your json you posted is exactly like that, your error is at the bottom, see this part:
{
"config": {
"optimize-autoloader": true,
"preferred-install": "dist",
"sort-packages": true
},
"minimum-stability": "dev",
"prefer-stable": true
} // HERE IS THE ERROR
{
"require": {
"phpoffice/phpspreadsheet": "^1.23"
},
"config": {
"platform": {
"php": "7.3"
}
}
}
You have to move the text inside the require (at the bottom) into the top where you also have require, same for config...
Your JSON should be like this:
{
"name": "laravel/laravel",
"type": "project",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"require": {
"php": "^7.3|^8.0",
"consoletvs/charts": "6.*",
"fruitcake/laravel-cors": "^2.0",
"guzzlehttp/guzzle": "^7.0.1",
"ladumor/laravel-pwa": "^0.0.3",
"laravel/framework": "^8.75",
"laravel/sanctum": "^2.11",
"laravel/tinker": "^2.5",
"phpoffice/phpspreadsheet": "^1.25",
"phpoffice/phpspreadsheet": "^1.23"
},
"require-dev": {
"facade/ignition": "^2.5",
"fakerphp/faker": "^1.9.1",
"laravel/sail": "^1.0.1",
"mockery/mockery": "^1.4.4",
"nunomaduro/collision": "^5.10",
"phpunit/phpunit": "^9.5.10"
},
"autoload": {
"psr-4": {
"App\\": "app/",
"Database\\Factories\\": "database/factories/",
"Database\\Seeders\\": "database/seeders/"
}
},
"autoload-dev": {
"psr-4": {
"Tests\\": "tests/"
}
},
"scripts": {
"post-autoload-dump": [
"Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
"#php artisan package:discover --ansi"
],
"post-update-cmd": [
"#php artisan vendor:publish --tag=laravel-assets --ansi --force"
],
"post-root-package-install": [
"#php -r \"file_exists('.env') || copy('.env.example', '.env');\""
],
"post-create-project-cmd": [
"#php artisan key:generate --ansi"
]
},
"extra": {
"laravel": {
"dont-discover": []
}
},
"config": {
"optimize-autoloader": true,
"preferred-install": "dist",
"sort-packages": true,
"platform": {
"php": "7.3"
}
},
"minimum-stability": "dev",
"prefer-stable": true
}
BUT, you can see you now have the same package, twice, with 2 different versions:
"require": {
"php": "^7.3|^8.0",
"consoletvs/charts": "6.*",
"fruitcake/laravel-cors": "^2.0",
"guzzlehttp/guzzle": "^7.0.1",
"ladumor/laravel-pwa": "^0.0.3",
"laravel/framework": "^8.75",
"laravel/sanctum": "^2.11",
"laravel/tinker": "^2.5",
"phpoffice/phpspreadsheet": "^1.25",
"phpoffice/phpspreadsheet": "^1.23"
},
You will have to know if phpoffice/phpspreadsheet needs to be ^1.25 or ^1.23. I will assume using 1.25 is fine
