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

I tried everything but nothing seems to work for me. Then, I check this link https://github.com/tymondesigns/jwt-auth/issues/1764

how to resolve this?

Answer 1

In order to install JWTAuth in Laravel 5.8 you need to use following

composer require tymon/jwt-auth:dev-develop

Answer 2

Yes, there's an open issue on github. Solution: composer require tymon/jwt-auth:1.0.0-rc.4.1

To install and properly use this with Laravel 5.8, you need "tymon/jwt-auth": "1.0.0-rc.4.1". NOT 0.5.x and NOT even 1.0.x.

I use it and everything just fine.
