Looks like you changed your composer.json before and did not run composer update after that.
can you show composer.json?

After
php composer.phar create-project --prefer-dist --stability=dev yiisoft/yii2-app-basic AppEngine
I updated it and then
php composer.phar require --prefer-dist yiisoft/yii2-mongodb "*"
This is composer.json:

Found the problem. mongodb extension does not seem to be available on packagist. We’ll fix it.

Must have been some temporary issue with packagist. Was not able to see the package minutes ago but now it is there:
https://packagist.org/packages/yiisoft/yii2-mongodb
Found the real cause of the problem:
Looks like you do not have the mongodb php extension installed that is required by yii2-mongodb package.
Composer now falls back to installing yii2-dev instead which provides yii2-mongodb without this dependency 
To fix this, install the mongodb php extension and run composer update
