title: how to install dependencies or use composer at all in windows
body: <p>I've installed composer via windows installer, and set the correct path  variables for php to wamp's php, now I created a composer.json( and later .phar) file</p>
  
  <p>and attempt to install dependencies listed there</p>
  
  <pre><code>{
  "name": "phpunit/php-unit",
  "require": {
      "php": "&gt;5.4.12",
      "phpunit/phpunit": "3.7.28"
  }
  }
  </code></pre>
  
  <p>this comes out of almost every command, including</p>
  
  <pre><code>php composer.phar install
  php composer.json install
  </code></pre>
  
  <p>i did ran this in windows cmd so im not sure if that affects anything.</p>
