Composer file could not be downloaded: failed to open stream: HTTP request failed!

 Error

[Composer\Downloader\TransportException]
The "http://packagist.org/p/symfony/class-loader$78539d95ddac0cc02514ed9cdf1515023dcd289b4f7e03ed948e868a1b02acf2.json" file could not be downloaded: failed to open stream: HTTP request failed!

The error means the composer is unable to process the request due to HTTP and we need to update

and add https instead of http.

Solution:

In your composer.json update following 

"repositories": [
    {
        "packagist": false
    },
    {
        "type": "composer",
        "url": "https://packagist.org/"
    }
],

Solution:2

Run this command to set https globally on the system.







composer config --global repos.packagist composer https://repo.packagist.org
