作曲家自動加載不加載GuzzleHttp \ ClientInterface

Question

我試圖使用Guzzle，但我發現了以下致命錯誤：

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

我與作曲家自動加載自動加載：

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); 

發生了什麼？

編輯

我composer.json：

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

我composer.lock

Answer 1

的命名空間狂飲4是GuzzleHttp在狂飲3的命名空間只是Guzzle。

一個composer.json的：

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

應該允許您運行的PHP腳本：

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); 

如果磁帶自動加載改變了命名空間也可能是你的作曲家的版本之後仍然失敗過時並且不承認PSR4自動加載。如果vendor/composer/autoload_psr4.php中沒有文件，請嘗試執行composer self-update後跟composer dump-autoload以查看問題是否已解決。
