'GuzzleHttp \ Collection'找不到

Question

我想要use this Google Analytics API tutori al，但它依賴於Guzzle。而我得到這個錯誤：

Fatal error: Class 'GuzzleHttp\Collection' not found in ../google-api-php-client/src/Google/Client.php on line 93 

但我已經安裝了狂飲：

>>php composer.phar require guzzlehttp/guzzle:~5.2 
./composer.json has been created

Generating autoload files 

這是我composer.json：

"require": { 
     "php": ">=5.4", 
     "google/auth": "v0.3", 
     "monolog/monolog": "^1.17", 
     "phpseclib/phpseclib": "~2.0", 
     "guzzlehttp/guzzle": "5.3.*" 
    },

你必須包括作曲的自動加載文件，如下所述：https://getcomposer.org/doc/01-basic-usage.md#autoloading

在您的主文件中，在頂部添加以下行（是前面任何需要這些文件的代碼）：

require __DIR__ . '/vendor/autoload.php';
