Kompozytor autoloader nie ładuje GuzzleHttp \ ClientInterface

Question

Próbuję użyć Guzzle, ale ja dostaję następujący błąd krytyczny:

Fatal error: Class 'GuzzleHttp\ClientInterface' not found in /var/www/myapp/vendor/guzzlehttp/guzzle/src/functions.php on line 13

mam autoloading z kompozytorem autoloaderze:

require 'vendor/autoload.php'; 

use Guzzle\Http\Client; 

$client = new Client(); 

$requests = Array(
    $client->createRequest('GET', 'ams1.myapp.com:8080/api/ffmpeg_make_snapshots.php'), 
    $client->createRequest('GET', 'ams2.myapp.com:8080/api/ffmpeg_make_snapshots.php'), 
    $client->createRequest('GET', 'ams3.myapp.com:8080/api/ffmpeg_make_snapshots.php') 
); 

$client->sendAll($requests); 

Co się dzieje?

EDIT

Moja composer.json:

{ 
    "require": { 
     "guzzlehttp/guzzle": "~4" 
    } 
} 

EDIT 2

Moja composer.lock

Answer 1

namespace do guzzle 4 jest GuzzleHttp w guzzle 3, nazw po prostu Guzzle.

composer.json od:

{ 
    "require": { 
     "guzzlehttp/guzzle": "~4" 
    } 
} 

powinno pozwolić na uruchomienie skryptu PHP:

require 'vendor/autoload.php'; 

use GuzzleHttp\Client; 

$client = new Client(); 

$requests = Array(
    $client->createRequest('GET', 'ams1.myapp.com:8080/api/ffmpeg_make_snapshots.php'), 
    $client->createRequest('GET', 'ams2.myapp.com:8080/api/ffmpeg_make_snapshots.php'), 
    $client->createRequest('GET', 'ams3.myapp.com:8080/api/ffmpeg_make_snapshots.php'), 
); 

$client->sendAll($requests); 

Jeśli autoloader nadal nie po zmianie nazw mogłoby się okazać, że twoja wersja kompozytora jest nieaktualny i nie rozpoznaje automatycznego ładowania. Jeśli w pliku vendor/composer/autoload_psr4.php nie ma pliku, spróbuj wykonać composer self-update, a następnie composer dump-autoload, aby sprawdzić, czy problem został rozwiązany.
