由于驱动程序丢失，无法安装yii2 mongodb扩展

Question

I'm trying to install yii2 mongodb extension, but I have this error when I run composer update

Problem 1
    - yiisoft/yii2-mongodb 2.1.1 requires ext-mongodb >=1.0.0 -> the requested PHP extension mongodb is missing from your system.
    - yiisoft/yii2-mongodb 2.1.0 requires ext-mongodb >=1.0.0 -> the requested PHP extension mongodb is missing from your system.
    - Installation request for yiisoft/yii2-mongodb ~2.1.0 -> satisfiable by yiisoft/yii2-mongodb[2.1.0, 2.1.1].

I know I need to have the driver installed but I have it, I know because of this

php -i | grep mongo
/etc/php5/cli/conf.d/20-mongo.ini,
mongo
mongo.allow_empty_keys => 0 => 0
mongo.chunk_size => 261120 => 261120
mongo.cmd => $ => $
mongo.default_host => localhost => localhost
mongo.default_port => 27017 => 27017
mongo.is_master_interval => 15 => 15
mongo.long_as_object => 0 => 0
mongo.native_long => 1 => 1
mongo.ping_interval => 5 => 5

and the extension was installed trought pecl, I have this info when I run

pecl info mongo

Answer 1

解决了，基本上我不知道有多个mongo扩展安装，Yii需要的是mongodb扩展，我从自制程序安装了一个，现在一切正常，谢谢！
