Composer Warning: This development build of composer is over 60 days old. It is recommended to update it by running

Question

When I try to run in the first time composer install i get :

[Composer\Downloader\TransportException] file could not be downloaded: SSL operation fail ed with code 1. OpenSSL Error messages: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed Failed to enable crypto failed to open stream: operation failed

I think i must update my composer but if i run composer self-update i get this Exception: [RuntimeException] SHA384 is not supported by your openssl extension, could not verify the phar file integrity

The result of my compser diagnose it's OK except:

Warning: This development build of composer is over 60 days old. It is recommended to update it by running "C:\Applications\bin\composer.phar self-update" to get the latest version.

Checking composer.json: WARNING No license specified, it is recommended to do so. For closed-source software you may use "proprietary" as license

Checking composer version: WARNING You are not running the latest stable version, run composer self-update to update (edece864e7e4c668dcad6601df70777882d22116 => 1.10.6)

Please Help me.

Yes, i solved this probleme by installing a new version of composer Command-line installation by steps in : https://getcomposer.org/download/ — Baissal, May 25 '20 at 10:57
