Problem 1
- Installation request for barryvdh/laravel-omnipay ^0.2.2 -> satisfiable by barryvdh/laravel-omnipay[v0.2.2].
- Can only install one of: guzzlehttp/guzzle[6.5.x-dev, 7.0.1].
- Can only install one of: guzzlehttp/guzzle[7.0.1, 6.5.x-dev].
- Can only install one of: guzzlehttp/guzzle[6.5.x-dev, 7.0.1].
- Conclusion: install guzzlehttp/guzzle 6.5.x-dev
- Installation request for guzzlehttp/guzzle (locked at 7.0.1, required as ^7.0.1) -> satisfiable by guzzlehttp/guzzle[7.0.1].

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

I downgraded and it required to install Laravel 7.
