title: Composer Failed to decode response: zlib_decode()
body: <p>I'm trying to install crudkit.com. This is my composer.json:</p>
  
  <pre><code>{
      "description" : "The CodeIgniter framework",
      "name" : "codeigniter/framework",
      "license": "MIT",
      "require": {
          "php": "&gt;=5.2.4"
      },
      "require-dev": {
          "mikey179/vfsStream": "1.1.*"
      }
  
  }
  </code></pre>
  
  <p>After that, I run the composer using:</p>
  
  <pre><code>$ sudo php composer.phar install
  </code></pre>
  
  <p>But I got error like this:</p>
  
  <pre><code>Installing dependencies (including require-dev)
  Failed to decode response: zlib_decode(): data error
  Retrying with degraded mode, check https://getcomposer.org/doc/articles/troubleshooting.md#degraded-mode for more info
  </code></pre>
  
  <p>Anyone know how to solve it?</p>
  
  <p>UPDATE:
  I have try to composer diagnose, and I got this:</p>
  
  <pre><code>Checking composer.json: FAIL
  The version field is present, it is recommended to leave it out if the package is published on Packagist.
  Checking platform settings: FAIL
  The OpenSSL library (0.9.8zc) used by PHP does not support TLSv1.2 or TLSv1.1.
  If possible you should upgrade OpenSSL to version 1.0.1 or above.
