php 7.1 problem

[hizone]

i try to install but i get that error:

Problem 1
- Installation request for cartalyst/tags 5.0.* -> satisfiable by cartalyst/tags[v5.0.0].
- cartalyst/tags v5.0.0 requires php >=7.0 -> your PHP version (7.1.11) overridden by "config.platform.php" version (5.6.25) does not satisfy that requirement.

what can i do?

Hello @Haizone

You seem to have something on your own composer.json file that's overriding the installed PHP version.

Something like

"config": {
    "platform": {
        "php": "5.6.25"
    }
}

Other than this, this is an issue on your end.

It's quite difficult to give a step by step guide on how to fix your issue.

Something on your end is enforcing Composer to use another version of PHP.

Usually that can happen if you update your main composer.json file and enforce it there.

I don't know how your application is built nor how it's performing this enforcement.

You can check this post on Stackoverflow that covers your issue as well.
