user37359: I am attempting to set up the PHP bitwasp library from the github repository:
https://github.com/Bit-Wasp/bitcoin-php
The installing instructions suggest I simply execute:
$ composer require bitwasp/bitcoin
I do have composer installed but I am getting the following error message:
Problem 1
    - Installation request for bitwasp/bitcoin dev-master -> satisfiable by bitwasp/bitcoin[dev-master].
    - Can only install one of: bitwasp/bitcoin[v0.0.29.1, dev-master].
    - Installation request for bitwasp/bitcoin v0.0.29.1 -> satisfiable by bitwasp/bitcoin[v0.0.29.1].
I do not practice PHP full time so I lack the experience of installing packages in that language and using composer. I would be grateful if someone could point me in the right direction.
EDIT
The suggestion has been made that the package is already installed. However, the following code sample which I got from another thread:
<?php
// failing to install bitwasp
use BitWasp\Bitcoin\Bitcoin;
use BitWasp\Bitcoin\Address;
use BitWasp\Bitcoin\Key\PrivateKeyFactory;

$network = Bitcoin::getNetwork();

$privateKey = PrivateKeyFactory::create(true);
$publicKey = $privateKey->getPublicKey();
$address = $publicKey->getAddress();

?>

is giving me PHP Fatal error:  Class 'BitWasp\Bitcoin\Bitcoin' not found.

user40723: You have it installed already. That's why it's saying you have the requirements met and don't need to download it again.
