[claytonferraz]

Q
Bug?	yes
New Feature?	no	yes
Framework	Laravel
Framework version	5.5.13
Package version	master
PHP version	7.1.7

Actual Behaviour

When I will install the package this error appears: Your requirements could not be resolved to an installable set of packages.

Problem 1

• Installation request for dingo/api ^0.10.0 -> satisfiable by dingo/api[v0.10.0].
• dingo/api v0.10.0 requires league/fractal 0.12.* -> satisfiable by league/fractal[0.12.0] but these conflict with your requirements or minimum-stability.

Expected Behaviour

installation in version 5.5 laravel

Steps to Reproduce

I'm using the composer command.

composer require dingo/api or composer require dingo/api:2.0.x@dev

Possible Solutions

Try composer update not require, require don't update dependencies
