 );

please let me know why is happened?.... we need to update composer?

it seems like there's a problem with the namespace?

Answer 1

It looks like it's a composer problem since the bundle declaration is already namespaced and I'm assuming you haven't monkied with how the AppKernel sets up it's autoloader.

Either you need to add the library to composer:

composer require vich/uploader-bundle:0.14.0

or if you've manually updated composer.json, you'll need to run:

composer update --lock

Which will install the dependency, update the lockfile, and re-generate your autoload.php file. These commands may or may not work depending on how you installed composer(may need to prepend commands with php composer.phar instead of composer). You'll need to figure that out for yourself. Also, you'll need to specify the version you want as well. I just chose the latest stable from packagist.
