Installation failed, reverting ./composer.json to its original content.

This log want to say to you that dependencies from those libraries doesn't match. Some modules need `symfony/console` `v2.6.*`, but other require `2.5.*`. — danopz, Jun 17 '15 at 11:07

Why doesn't it install?

The installed dependencies of the Zend Skeleton use symfony/console in version 2.6.6.

"anahkiasen/rocketeer" requires "illuminate/console" in a version ~4.2, which itself requires "symfony/console" in version 2.5.*.

Composer cannot install the new package because the installed version 2.6.6 of symfony/console will be kept, but is incompatible to the requirement of the depencencies of the new package (2.5.* does not allow version 2.6.6).

You can try to manually add your new package and then run composer update. If by chance the skeleton package would also allow symfony/console in version 2.5, this would resolve to an installable set of packages.

Fair enough, after second glance at the message and digging up some `depends` commands of composer, this cleared out for me. Thanks for your time. Any decent tools for remote deployment (cuz that Rocketeer.....) — Antoniossss, Jun 17 '15 at 14:08
