【问题描述】：

我在 ubuntu 14.4 上使用 Lumen 微框架，当我想安装 monogodb 包表单 this link 时出现如下错误：

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.

我该如何解决？

【解决方案1】：

你没有安装 php mongodb 驱动/扩展

使用这个

sudo apt-get install php5-mongo

如果你使用的是 php 5

【讨论】：

我收到错误E: Package 'php5-mongo' has no installation candidate
完全错误是Package php5-mongo is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'php5-mongo' has no installation candidate
请朋友们帮帮我
抱歉一直很忙。转到终端并键入 php -m 并查看已安装的模块中是否有 mongo
你使用的是哪个版本的php。

【解决方案2】：

当我运行php -m 时，我得到了：
