i recently installed laravel 5.8 for one of my projects but unfortunately i'v some problem in installing packages that i have never had before.. for exp i want to install jrean package for verification users but i get this error :

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

Problem 1

- Conclusion: don't install jrean/laravel-user-verification V8.0.0

- Conclusion: remove laravel/framework v5.8.35

- Installation request for jrean/laravel-user-verification ^8.0 -> satisfiable by jrean/laravel-user-verification[8.0.x-dev, V8.0.0].

- Conclusion: don't install laravel/framework v5.8.35

- jrean/laravel-user-verification 8.0.x-dev requires illuminate/support ^6.0 -> satisfiable by 

illuminate/support[6.x-dev, v6.0.0, v6.0.1, v6.0.2, v6.0.3, v

6.0.4].

- don't install illuminate/support 6.x-dev|don't install laravel/framework v5.8.35

- Installation request for laravel/framework (locked at v5.8.35, required as 5.8.*) -> satisfiable by laravel/framework[v5.8.35].

Installation failed, reverting ./composer.json to its original content.*

even i try this in my composer.json
