i am trying to install liuggio/ExcelBundle
but i got this error while installing :

Your requirements could not be resolved to an installable set of packages.

Problem 1
- doctrine/annotations v1.4.0 requires php ^5.6 || ^7.0 -> your PHP version (5.5.9) does not satisfy that requirement.
- doctrine/annotations v1.4.0 requires php ^5.6 || ^7.0 -> your PHP version (5.5.9) does not satisfy that requirement.
- Installation request for doctrine/annotations (locked at v1.4.0) -> satisfiable by doctrine/annotations[v1.4.0].

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