php artisan not working

Hi I am beggining with laravel and I was using sqlite database but now I am switching to mysql, so I changed the app/database.php file accordingly and when Im trying to migrate the tables Im getting these errors.

[Illuminate\Database\QueryException] SQLSTATE[42S02]: Base table or view not found: 1146 Table 'elbeplus.categories' doesn't exist ( SQL: select * from 'categories')

[PDOException] SQLSTATE[42S02]: Base table or view not found: 1146 Table 'elbeplus.categories' doesn't exist.

Even more weird is im getting this same two errors just when Im trying to access php artisan not even migrating..

Any suggestions? Thanks.
