答

转到您的Routes.php文件并找到

Go to your Routes.php file and find

$routes->set404Override();

现在，如果您只想显示一条错误消息，请输入

Now , If you want to display just an error message then write

    $routes->set404Override(function(){
    echo "your error message";
});

代替

$routes->set404Override();

或如果您想返回视图，则编写如下:

Or If you want to return a view then write like below:

$routes->set404Override(function(){
    return view('your_filename');
});

代替

$routes->set404Override();
