Installing cakedc/users on CakePHP 3.1 version conflict

Question

I'm trying to install Cake dc users on a Cakephp 3.1

That's a part of my composer.json that I'm almost sure that is properly setup mantain the cake version to 3.1:

    "require": {
    "php": ">=5.4.16",
    "cakephp/cakephp": "~3.1",

I used the following command to setup cake:

composer create-project cakephp/app ar2016-2 3.1.*

and that's the result I get when I try to install DCUsers with the composer:

---

composer require cakedc/users:~3.1.0 ./composer.json has been updated

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 - Conclusion: remove cakephp/cakephp 3.2.1 - Conclusion: don't install cakephp/cakephp 3.2.1 - cakedc/users 3.1.0 requires cakephp/cakephp ~3.1.0 -> satisfiable by cakephp/cakephp[3.1.0, 3.1.0-RC1, 3.1.0-beta, 3.1.0-beta2, 3.1.1, 3.1.10, 3.1.2, 3.1.3, 3.1.4, 3.1.5, 3.1.6, 3.1.7, 3.1.8, 3.1.9]. ...

It looks that it detects CakePHP 3.2.1 but everywhere I check show me that I'm using the proper 3.1. version. Any Idea?

Thanks in advance, David

Answer 1

Thanks for the answer but it's just fixed, it was a problem of the plugin itself and cakedc fixed.

Answer 2

I'd doubt that it shows that you've installed 3.1 anywhere at all, because the latest release is 3.2.1 and, ~3.1 means >= 3.1 and < 4.0.0, and therefore I'm pretty sure that you have the latest version installed, ie 3.2.1, a quick bin/cake will probably confirm that.

The cakedc/users version that you have requested, requires cakephp/cakephp:3.1.*, which means >= 3.1 and < 3.2, hence the error.

https://getcomposer.org/doc/articles/versions.md#wildcard

So either use the master branch of the plugin (it requires cakephp/cakephp:~3.1) until a proper release is issued, or use a more specific version constraint for the CakePHP framework, like 3.1.*
