I found solution here, downgrade my php mongo extension update compsoer.phar but still getting same error. What I am doing wrong ?

Here is my composer.json file:

"require": {
    "php": ">=5.3.3",
    "symfony/symfony": "2.5.*",
    "doctrine/orm": "~2.2,>=2.2.3",
    "doctrine/doctrine-bundle": "~1.2",
    "twig/extensions": "~1.0",
    "symfony/assetic-bundle": "~2.3",
    "symfony/swiftmailer-bundle": "~2.3",
    "symfony/monolog-bundle": "~2.4",
    "sensio/distribution-bundle": "~3.0",
    "sensio/framework-extra-bundle": "~3.0",
    "incenteev/composer-parameter-handler": "~2.0",
    "doctrine/doctrine-fixtures-bundle": "2.2.*",
    "doctrine/migrations": "1.0.*@dev",
    "doctrine/doctrine-migrations-bundle": "2.1.*@dev",
    "hautelook/alice-bundle": "~0.2",
    "nelmio/alice": "~1.7",
    "stof/doctrine-extensions-bundle": "1.2.*@dev",
    "knplabs/knp-menu-bundle": "~2.0",
    "doctrine/mongodb-odm": "1.0.*@beta",
    "doctrine/mongodb-odm-bundle": "3.0.*@beta"
},

Edit

I even try to change "minimum-stability" property. Downgrade ext-mongo to 1.4.5 and 1.2.12 versions. Still have the same error.

SOLVING

Solve this by run in cli : sudo apt-get install php5-mongo

Answer 1

are you sure you have the mongo extension ?

run this from console

 php -i | grep mongo

are there the mongo configs ?

if so add

phpinfo();

to your app/app_dev.php and check if Symfony(apache) is using another php than your shell PATH

UPDTE:

as pointed out in comments, your apache uses another php than you expect point the apache to the correct php extension path in httpd.conf
