Problem 1 - spatie/crawler[6.0.0, ..., v6.x-dev] require guzzlehttp/psr7 ^1.7 -> found guzzlehttp/psr7[1.7.0, ..., 1.x-dev] but it conflicts with your root composer.json require (^2.4). - Root composer.json requires spatie/crawler ^6.0 -> satisfiable by spatie/crawler[6.0.0, 6.0.1, 6.0.2, v6.x-dev].
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions. You can also try re-running composer require with an explicit version constraint, e.g. "composer require spatie/crawler:*" to figure out if any version is installable, or "composer require spatie/crawler:^2.1" if you know which you need.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
