$ composer require los/loslog

@samsonasik I just created 2 new skeleton with different combination os packages and could install this module in both (using php 7.0.2). Could you send me your composer.json? Thanks!

[samsonasik]

this is my composer.json:

"require": {
        "php": "^5.5 || ^7.0",
        "roave/security-advisories": "dev-master",
        "zendframework/zend-expressive": "~1.0.0@rc || ^1.0",
        "zendframework/zend-expressive-helpers": "^2.0",
        "zendframework/zend-stdlib": "~2.7",
        "zendframework/zend-expressive-fastroute": "^1.0",
        "zendframework/zend-servicemanager": "^2.7.3 || ^3.0",
        "ocramius/proxy-manager": "^1.0",
        "zendframework/zend-expressive-platesrenderer": "^1.0"
    },
    "require-dev": {
        "phpunit/phpunit": "^4.8",
        "squizlabs/php_codesniffer": "^2.3",
        "filp/whoops": "^1.1 || ^2.0"
    },

@samsonasik The default installer uses service manager 2.5:

"zendframework/zend-servicemanager": "^2.5",

But specifying zend-servicemanager v3, conflicts with zend-log which requires service manager ~2.5:

Problem 1
    - Installation request for zendframework/zend-log ~2.6 -> satisfiable by zendframework/zend-log[2.6.0].
    - Conclusion: remove zendframework/zend-servicemanager 3.0.2
    - Conclusion: don't install zendframework/zend-servicemanager 3.0.2
    - zendframework/zend-log 2.6.0 requires zendframework/zend-servicemanager ~2.5 -> satisfiable by zendframework/zend-servicemanager[2.7.3, 2.7.4].
    - Can only install one of: zendframework/zend-servicemanager[2.7.3, 3.0.2].
    - Can only install one of: zendframework/zend-servicemanager[2.7.4, 3.0.2].
    - Installation request for zendframework/zend-servicemanager == 3.0.2.0 -> satisfiable by zendframework/zend-servicemanager[3.0.2].

Maybe i need to create a new version for loslog (2.1) that supports servicemanager v3 and it's dependencies.
