I am currently running Drush 7 and its working fine for D7.
But I want to run it for D8 site. I have also seen many post where it is mentioned that Drush 7 support D8 but its not true.
So i am trying to install Drush 8.
Try to run below command
composer global require drush/drush:8.*
Or
composer require drush/drush:dev-master
./composer.json has been created 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 drush/drush dev-master -> satisfiable by drush/drush[dev-master]. - drush/drush dev-master requires consolidation/robo dev-master -> satisfiable by consolidation/robo[dev-master] but these conflict with your requirements o r minimum-stability. Installation failed, deleting ./composer.json.
But unable to get success. Any suggestion how achieve this?
