Attempted to load class "ObjectID" from namespace "MongoDB\BSON"

Question

I'm trying to use DoctrineMongoDBBundle but it gives me this error :

Attempted to load class "ObjectID" from namespace "MongoDB\BSON". Did you forget a "use" statement for another namespace?

I've searched all over for a reason, but I could not find why I get this error.

My mongodb is installed alright, a mongodb status tells me it's active. I think I correctly set up the classes... etc. Where can the error be coming from?

Stack trace :

Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "ObjectID" from namespace "MongoDB\BSON". Did you forget a "use" statement for another namespace?

php --ri mongodb | grep version outputs:

MongoDB extension version => 1.3.2, libbson bundled version => 1.8.1, libmongoc bundled version => 1.8.1

Simple example to demonstrate :

<?php

namespace Acme\StoreBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Response;
use MongoDB\BSON\ObjectID; //Adding this or not doesn't change anything

class DefaultController extends Controller
{
    /**
     * @Route("/")
     */
    public function indexAction()
    {
        var_dump(new MongoDB\BSON\ObjectID); die();
        return $this->render('AcmeStoreBundle:Default:index.html.twig');
    }
}

And composer.json requires got :

"require": {
        "php": ">=5.5.9",
        "alcaeus/mongo-php-adapter": "^1.1",
        "doctrine/doctrine-bundle": "^1.6",
        "doctrine/mongodb-odm": "^1.2",
        "doctrine/mongodb-odm-bundle": "^3.4",
        "doctrine/orm": "^2.5",
        "incenteev/composer-parameter-handler": "^2.0",
        "sensio/distribution-bundle": "^5.0.19",
        "sensio/framework-extra-bundle": "^3.0.2",
        "symfony/monolog-bundle": "^3.1.0",
        "symfony/polyfill-apcu": "^1.0",
        "symfony/swiftmailer-bundle": "^2.3.10",
        "symfony/symfony": "3.3.*",
        "twig/twig": "^1.0||^2.0"
    },

Do you have the mongo db driver installed? (Sorry, just a sanity check.) — Ollie in PGH, Nov 17 '17 at 15:52
@ASOlivieri yes. php --ri mongodb | grep version outputs MongoDB extension version => 1.3.2, libbson bundled version => 1.8.1, libmongoc bundled version => 1.8.1 — , Nov 17 '17 at 15:58
Stack trace should hint where the error's coming from. As a side note, instead of claiming "I did everything correctly" you will be better with posting the code you **think** you did right. The error proves something's wrong there. — Alex Blex, Nov 17 '17 at 16:03
@AlexBlex I added the stack trace. And I tried so many things that I lost count, that's why I didn't write what I tried exactly. And I don't think I tried everything, just the obvious things found on the web when I wrote my error on google... — , Nov 17 '17 at 16:07
Confirm it works in both cli and fpm: `php -r 'var_dump(new \\MongoDB\\BSON\\ObjectID);'` should result with no error. Then add a first line after ` — Alex Blex, Nov 17 '17 at 18:07
@AlexBlex your first code results in no error in the terminal of the project. Second on the other-hand gave me the same error as the original post when I wrote it at the start of my controller (as I have no index.php anywhere x)) — , Nov 17 '17 at 19:22
You need to restart php-fpm or apache whatever you use for http requests — Alex Blex, Nov 17 '17 at 19:25
@AlexBlex already did so many times while trying to debug the problem ... — , Nov 17 '17 at 19:36
Then the extension is not in the fpm/apache php config. Add it there the same way you did for cli. — Alex Blex, Nov 17 '17 at 19:42
@AlexBlex I do have in my /etc/php/7.0/apache2/php.ini : extension_dir = "./usr/lib/php/20151012/" and extension=mongodb.so — , Nov 17 '17 at 19:47
Apparently it is not loaded for some reason. Put `phpinfo() ` in index.php to confirm which configs were loaded and the extension is enabled. — Alex Blex, Nov 18 '17 at 01:04

Hello you need to include "alcaeus/mongo-php-adapter": "^1.1" as part of your packages and also expose the expected mongo extension as a failure resolution like

  "provide": {
    "ext-mongo": "1.6.12"
  },

a complete composer file may be like

{
  "require": {
    "php": "^7.1.3",
    "ext-mongodb": ">=1.1.2",
    "alcaeus/mongo-php-adapter": "^1.1",
    "doctrine/mongodb-odm-bundle": "^3.3",
    ...
  },
  "provide": {
    "ext-mongo": "1.6.12"
  }
  ...
}

Thank you for trying but I already have that set up and it doesn't work :) I didn't have ext-mongodb in the require section tho, but adding it doesn't correct the error. I did have provide. – Nov 17 '17 at 20:05
thats wear i have a project with that configuration working just fine, it may be something else on your versions or configurations, maybe the extension is not enabled correctly for the webserver only for cli – bitgandtter Nov 17 '17 at 20:15
