I Want to install Drush on my MAC, I followed these steps: "https://www.drupal.org/node/1674222" only I got an error when I run "composer install" in the Drush directory.
I downloaded Drush from the Drush Github (https://github.com/drush-ops/drush)
The project is about to make a custom Drush command to export old Drupal project settings (.yml files) to a new project.
The error is something about there is no version set? I found this: "https://drupal.stackexchange.com/questions/241431/how-do-i-resolve-this-installation-error" and I tried to downgrade the version but still the same error.
The error message:
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Installation request for drush/drush No version set (parsed as 1.0.0) -> satisfiable by drush/drush[No version set (parsed as 1.0.0)].
- drupal/core 8.7.x-dev conflicts with drush/drush[No version set (parsed as 1.0.0)].
