I can\'t use a single command on it, it always return the error:

Answer 1

I have received the same error in routes.php. I have given the wrong Route.

I put Route::get('/admin' , AdminController@index); instead of Route::get('/admin' , 'AdminController@index');

I forgot single quotes. Please check yours.
