Could'nt install on Laravel 9

[anuradhan]

i'm getting following error while installing on laravel 9

Your requirements could not be resolved to an installable set of packages.

Problem 1
- Root composer.json requires tabuna/vesta-api 2.0 -> satisfiable by tabuna/vesta-api[2.0].
- tabuna/vesta-api 2.0 requires guzzlehttp/guzzle ^6.5 -> found guzzlehttp/guzzle[6.5.0, ..., 6.5.x-dev] but it conflicts with your root composer.json require (^7.5).

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
