Eloquent DB类为null

When I try to use he DB class of eloquent i get this error :

Call to a member function raw() on null

Code :

use Illuminate\Support\Facades\DB;
...
DB::raw("count(id_annonce)")
...

I already tried updating composer and frameworks

You have to use Capsule to init the DB connection and boot eloquent. Anyway you can use an alias to call it DB if you prefere.
