Laravel: Route [login] not defined

Looks like you're using route('login') to create a link to the login page or in form.

If you're using it in a link, just name get() route:

Route::get('login', ['as' => 'login', 'uses' => 'LoginController@getView']);

If you're using the route() helper in a form, do this for the post() route.

You can use the artisan comp php artisan make:auth to scaffold the authentication pages needed.

You can find the documentation for that here, https://laravel.com/docs/5.4/authentication
