I was trying to install tymon/jwt-auth with laravel 5.6.4 using composer
composer require tymon/jwt-auth
but it is showing some error like this:
Using version ^0.5.12 for tymon/jwt-auth
./composer.json has been updated
Loading composer repositories with package information

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

Installation failed, reverting ./composer.json to its original content.
Update:
Firstly I was trying composer update command adding some specific version of dependencies in composer.json file. Like "tymon/jwt-auth": "0.5.*" and "barryvdh/laravel-cors": "^0.8.2".
After that I was trying composer require tymon/jwt-auth not removing the lines with specific version of tymon/jwt-auth and barryvdh/laravel-cors.
After removing the lines from composer.json file with specific versions of tymon/jwt-auth the
composer require tymon/jwt-auth
command is working fine.
Thanks
回答1:
The package tymon/jwt-auth doesn't offer a stable version for use with Laravel 5.6 just yet, that's why composer can't resolve the dependency requirements.
If you check their releases they do have an RC (Release Candidate) available with support for Laravel 5.5 and 5.6. The one you would be interested in should be 1.0.0-rc.2.
