title: Pytube library - Receiving "pytube.exceptions.RegexMatchError: regex pattern" error when attempting to access video data
body: <p>When attempting to access data such as the "title" of a Youtube video using the pytube API library, I am receiving the following error</p>
  
  <blockquote>
    <p>pytube.exceptions.RegexMatchError: regex pattern (yt.akamaized.net/)\s*\|\|\s*.<em>?\s</em>c\s*&amp;&amp;\s<em>d.set([^,]+\s</em>,\s*(?P[a-zA-Z0-9$]+)() had zero matches</p>
  </blockquote>
  
  <p>Here is the code that I am using which is providing the error above.</p>
  
  <pre><code>import sys  
  import pytube
  
  link = input('Enter url: ') # url is: https://www.youtube.com/watch?v=KSbj-cFtFPA
  yt = pytube.YouTube(link)
  print(yt.title)
  
  sys.exit()
  </code></pre>
  
  <p>Might anyone know how to resolve this error? I have done some on-line searching, the answers provided were not definitive and did not work when I try. </p>
  
  <p>Note: I tried to uninstall pytube and re-install it but that did not fix the issue. </p>
