Not working with Elastic Search 6.0

[gecas]

Tried to install this package on my lumen app with elasticserach/elasticsearch package version 6.0,got this:
Using version ^1.3 for basemkhirat/elasticsearch
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- Installation request for elasticsearch/elasticsearch (locked at v6.0.1, required as ^6.0) -> satisfiable by elasticsearch/elasticsearch[v6.0.1].
- basemkhirat/elasticsearch 1.3 requires elasticsearch/elasticsearch ^5.0 -> satisfiable by elasticsearch/elasticsearch[5.0.x-dev].
- basemkhirat/elasticsearch 1.3.1 requires elasticsearch/elasticsearch ^5.0 -> satisfiable by elasticsearch/elasticsearch[5.0.x-dev].
- Conclusion: don't install elasticsearch/elasticsearch 5.0.x-dev
- Installation request for basemkhirat/elasticsearch ^1.3 -> satisfiable by basemkhirat/elasticsearch[1.3, 1.3.1].

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