title: ImportError: No module named http_client
body: <p>I recently tried to start working with Pyrebase and after installing Python 2.7.13 and installing Pyrebase, the module http_client is missing and therefore cannot import HTTPConnection. I tried uninstalling pyrebase and reinstalling it to see if then all the the modules would be included this time but i still get the same import error stating that the module http_client is nonexistant. Any ideas? </p>
  
  <p>Here is the code:</p>
  
  <pre><code>import pyrebase
  
  config = {
     "apiKey": "AIzaSyBYJ9WC68XJg6jGwAGwwxT3wcvGAti4FOg",
     "authDomain": "app-2-b1b3e.firebaseapp.com",
     "databaseURL": "https://app-2-b1b3e.firebaseio.com/",
     "storageBucket": "app-2-b1b3e.appspot.com"
  }
  
  fb = pyrebase.initialize_app(config)
  firebase = fb.database()
  def dataSentTest():
      data = {"name": "Mortimer 'Morty' Smith"}
      firebase.child("users").child("Morty").set(data)
  
  dataSentTest()
  </code></pre>
  
  <p>Here is the error message:</p>
