Your requirements could not be resolved to an installable set of packages. Problem 1 - Only one of these can be installed: illuminate/support[v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev, v10.0.0, ..., 10.x-dev, v11.0.0, ..., 11.x-dev], laravel/framework[v10.0.0, ..., 10.x-dev]. laravel/framework replaces illuminate/support and thus cannot coexist with it. - morningtrain/economic v1.0.0 requires illuminate/support ^11.0 -> satisfiable by illuminate/support[v11.0.0, ..., 11.x-dev]. - Root composer.json requires morningtrain/economic ^v1.0 -> satisfiable by morningtrain/economic[v1.0.0]. - Root composer.json requires laravel/framework 10.* -> satisfiable by laravel/framework[v10.0.0, ..., 10.x-dev].
