Laravel 5.8 issue

[anishbangalore]

Dear Friends,

How can I get the Laravel 5.8 supported version through composer?

This is I am getting while I try using composer,

composer require barryvdh/laravel-async-queue
Using version ^0.7.2 for barryvdh/laravel-async-queue
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
