I am following the setup instructions in the readme file. but when I get to the step to run composer install, i recieve errors. Composer version 1.2.0
Problem 1
- Installation request for aleksip/plugin-data-transform dev-master -> satisfiable by aleksip/plugin-data-transform[dev-master].
- aleksip/plugin-data-transform dev-master requires pattern-lab/patternengine-twig ^2.0.0 -> satisfiable by pattern-lab/patternengine-twig[v2.0.0] but these conflict with your requirements or minimum-stability.
When I update the jason file with the new versions, and run composer update, I get php error:
Loading composer repositories with package information
Updating dependencies (including require-dev)
- Installing pattern-lab/core (v2.7.0)
Loading from cache
