No PSR-17 request factory found on exchanger instantiation

[Federico Liva]

$exchanger = new \Exchanger\Service\ExchangeRatesApi();

I got this error:

No PSR-17 request factory found. Install a package from this list: https://packagist.org/providers/psr/http-factory-implementation

I don't understand why.

Have you done installation procedure in your project ?

[Federico Liva]

Yes, same issue with:

$client = new Http\Client\Curl\Client();
$exchanger = new Exchanger\Service\ExchangeRatesApi($client);

For me it is working, doing the following :

mkdir test && cd test
composer require php-http/curl-client nyholm/psr7 php-http/message florianv/exchanger

Then i created a test.php file :

<?php

include "vendor/autoload.php";
$exchanger = new \Exchanger\Service\ExchangeRatesApi();
var_dump($exchanger);

I do get an exchanger instance when i run the script.
php test.php output :

me@host:~/projects/test$ php test.php

@fede91it You need to install a package from the list, as stated in the error, for example nyholm/psr7.

Installing nyholm/psr7 it worked, sorry and thank you
