Answer 1

Just follow the documentation, you must have installed php7.2.5

Update your laravel/framework dependency to ^7.0 in your composer.json file.

In addition, update your nunomaduro/collision dependency to ^4.1,

phpunit/phpunit dependency to ^8.5,

facade/ignition to> `^2.0

After that as next step.

The report and render methods of your application's App\Exceptions\Handler class should accept instances of the Throwable interface instead of Exception instances:

use Throwable; // add this line

public function report(Throwable $exception); // replace Exception with Throwable
public function render($request, Throwable $exception); // replace Exception with Throwable

after that run

composer update

Answer 2

Update The following packages

"nunomaduro/collision": "^4.1",
"phpunit/phpunit": "^8.5",

"laravel/ui": "^2.0",

"facade/ignition": "^2.0",

"laravel/framework": "^7.0",
