  Potential causes:
   - A typo in the package name
   - The package is not available in a stable-enough version according to your minimum-stability setting

  <p>All I have globally installed is:</p>
  
  <pre><code>{
      "require": {
          "laravel/lumen-installer": "~1.0"
      }
  }
  </code></pre>
  
  <p>I have tried globally requiring guzzlehttp/streams, and also tried requiring the latest version of laravel, but to no help.</p>
  
  <p>My machine is pretty new, and I haven't done anything wrt composer until now.</p>
  
  <p>How do I solve this problem?</p>
