In summary laracasts/generators depends on illuminate/support v6.0.0 - v10.9.0 which is not loaded.

how should i solve this conflict?

as error says : i have tried run this command with -W option which is : composer require laracasts/generators:dev-master --dev -W and same error has occured :

- Root composer.json requires laracasts/generators dev-master -> satisfiable by laracasts/generators[dev-master].
    - laracasts/generators dev-master requires illuminate/support ~6.0|~7.0|~8.0|~9.0|^10.0 -> found illuminate/support[v6.0.0, ..., v6.20.44, v7.0.0, ..., v7.30.6, v8.0.0, ..., v8.83.27, v9.0.0, ..., v9.52.7, v10.0.0, ..., v10.9.0] but these were not loaded, likely because it conflicts with another require.
