Your requirements could not be resolved to an installable set of packages.
Problem 1
- flugger/laravel-responder[v3.1.0, ..., v3.1.1] require illuminate/contracts 5.1.* || 5.2.* || 5.3.* || 5.4.* || 5.5.* || 5.6.* || 5.7.* || 5.8.* || ^6.0 || ^7.0 -> found illuminate/contracts[v5.1.1, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev] but these were not loaded, likely because it conflicts with another require.
- flugger/laravel-responder[v3.1.2, ..., v3.1.3] require league/fractal ^0.17.0 -> found league/fractal[0.17.0] but the package is fixed to 0.19.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
- Root composer.json requires flugger/laravel-responder ^3.1 -> satisfiable by flugger/laravel-responder[v3.1.0, v3.1.1, v3.1.2, v3.1.3].
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
