[FIXED] Can not install doctrine/mongodb-odm-bundle

Issue

I want to install doctrine/mongodb but I get error:

Using version ^4.2 for doctrine/mongodb-odm-bundle
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)

Installation failed, reverting ./composer.json to its original content.

I am using this tutorial https://symfony.com/doc/master/bundles/DoctrineMongoDBBundle/installation.html#install-the-bundle-with-composer Thank you https://www.php.net/manual/en/mongodb.installation.windows.php

Solution

As you can see in the output composer tries install doctrine/mongodb-odm-bundle which depends on doctrine/mongodb-odm which requires mongodb extension version 1.5+ installed on your system.

Hint from the tutorial

So, lets go https://docs.mongodb.com/drivers/php#installation :)
