When I type composer require drupal/entity, this is the result:

Your requirements could not be resolved to an installable set of packages.

Problem 1
    - phpunit/phpunit-mock-objects dev-master requires php ^7.0 -> your PHP version (5.6.25) does not satisfy that requirement.

I am running a fresh Drupal 8.2.6 install and PHP 5.6 is a requirement. Why is it having a problem with Drupal core itself, and am I being forced to upgrade to PHP 7.0? I can't do that on Acquia hosting.

I basically had to do this instead:

composer require drupal/entity:1.0.0.0-alpha4

Or I could also do:

composer require drupal/entity:^1.0

Is Composer unable to determine version from tags? I can't tell why it was selecting 0.1.0.

Always specify a version constraint ("^1.0" is fine).
Here the problem is possibly because drupal/entity was also a core module initially.

Status: Fixed » Closed (fixed)

Automatically closed - issue fixed for 2 weeks with no activity.

Title: Cannot install via Composer / Acquia BLT » Cannot install via Composer
Category: Support request » Bug report

This is a bug, as composer is the officially recommended (not just preferred) way to install and manage Drupal core, contrib modules and manage libraries and dependencies.

As of current 8.x-1.0-alpha4 version, the correct command to install this module via composer would be (as indicated above):

composer require drupal/entity:^1.0

This should be mentioned on the module page and the README as well to save users time and troubles.

Great Work!

I am a little bit lost...
If I understand well, entity is no more in core?
This mean that if, for exemple, we use node we must do composer require drupal/entity:^1.0?
Or, maybe, this external entity module contains only extra feature that are used by some other modules (like media_entity)?

Could you kindly clarify this topic.

Thank you

From the project page:

  • The Drupal 8 core Entity API is significantly improved, so most of the features provided by the Drupal 7 version are already present in Drupal core.
  • The Drupal 8 version of the Entity API module is used for improvements to Drupal 8's Entity API which will be moved to Drupal core one day (development ongoing)

I think this is still a bug or at least a very unfortunate decision. I just installed LOTS of Drupal modules via composer. All via "require drupal/". The ONLY single module where this command isnt sufficient is the Entity module where you have to specify a version. I don't think it makes much sense that this module behaves different than any other Drupal module out there.

Thanks for considering this.

Struggled today to install this module. It would be nice to have a note on the project page that indicates the module version needs to be included for composer.
