I have a Drupal installation within a Docker container, with Composer and Drush installed. I'd like to install the Entity-API module (https://www.drupal.org/project/entity), and I start off with:
composer require drupal/entity
This gives me an error:
Using version ^0.1.0 for drupal/entity
./composer.json has been updated
> DrupalProject\composer\ScriptHandler::checkComposerVersion
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
- Can only install one of: drupal/core[8.5.6, 8.0.x-dev].
- Can only install one of: drupal/core[8.0.x-dev, 8.5.6].
- Can only install one of: drupal/core[8.0.x-dev, 8.5.6].
- drupal/entity 0.1.0 requires drupal/core <8.1.0 -> satisfiable by drupal/core[8.0.x-dev].
- Installation request for drupal/entity ^0.1.0 -> satisfiable by drupal/entity[0.1.0].
- Installation request for drupal/core (locked at 8.5.6, required as ~8.5.3) -> satisfiable by drupal/core[8.5.6].
Installation failed, reverting ./composer.json to its original content.
My Drupal version is 8.5.6 and I'm using the latest version of Composer, installed from https://getcomposer.org/installer
How would I get this installed using Composer? Tx
