Answer 1

this is an open issue you can find it here : github Composer issues 2624

Maybe some solutions in comments may help you.

Try :

Update composer.phar with

composer.phar self-update

Answer 2

First off, if you're running a web filter, especially K9 Web Protection, uninstall that first and retry. If the problem persists, read ahead:

The problem is that Composer downgrades to http requests after the first https request to the server. This is done to improve performance/speed and to ensure file integrity/security via the sha256 hashes. In any case, this will cause a 10053 error (errno=10053 An established connection was aborted by the software in your host machine ... failed to open stream: HTTP request failed!) on some machines.

The reason this happens to some people and not others seems to be the manner in which your ISP handles http requests. In my case, they're re-routed through a caching proxy; which doesn't work well with the way Composer crafts its http requests. That's what happened with me - others may have a different cause. In any case, the fix is to force Composer to use https requests instead of http requests:

Add the following to your Composer installation's config file (composer.json). In Windows, you may find this file at C:\Users{Your Username}\AppData\Roaming\Composer.

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

Then go ahead and create your project again with the same command you had used: php composer.phar install. It should work now.
