我在ubuntu 14.4上使用Lumen微框架，当我想安装monogodb packege form this link时，我收到如下错误：
Your requirements could not be resolved to an installable set of packages.
Problem 1
- jenssegers/mongodb v3.0.0 requires mongodb/mongodb ^1.0.0 -> satisfiable by mongodb/mongodb[1.0.0, 1.0.1].
- jenssegers/mongodb v3.0.1 requires mongodb/mongodb ^1.0.0 -> satisfiable by mongodb/mongodb[1.0.0, 1.0.1].
- jenssegers/mongodb v3.0.2 requires mongodb/mongodb ^1.0.0 -> satisfiable by mongodb/mongodb[1.0.0, 1.0.1].
- mongodb/mongodb 1.0.1 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.
- mongodb/mongodb 1.0.0 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.
- Installation request for jenssegers/mongodb ^3.0 -> satisfiable by jenssegers/mongodb[v3.0.0, v3.0.1, v3.0.2].
To enable extensions, verify that they are enabled in those .ini files:
- /etc/php5/cli/php.ini
- /etc/php5/cli/conf.d/05-opcache.ini
- /etc/php5/cli/conf.d/10-pdo.ini
- /etc/php5/cli/conf.d/20-curl.ini
- /etc/php5/cli/conf.d/20-gd.ini
- /etc/php5/cli/conf.d/20-json.ini
- /etc/php5/cli/conf.d/20-mcrypt.ini
- /etc/php5/cli/conf.d/20-mysql.ini
- /etc/php5/cli/conf.d/20-mysqli.ini
- /etc/php5/cli/conf.d/20-pdo_mysql.ini
- /etc/php5/cli/conf.d/20-readline.ini
- /etc/php5/cli/conf.d/mongo.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
Installation failed, reverting ./composer.json to its original content.
