  <p>Since I was getting permission denied, I tried running it with sudo, </p>
  
  <pre><code>abcdefg@HAL9000:~$ sudo pip install beautifulsoup4
  Downloading/unpacking beautifulsoup4
    Cannot fetch index base URL http://pypi.python.org/simple/

  <p>I know I can install it without pip as well, but I encountered this problem while installing requests as well, so I want to know the solution</p>
  
  <p>Thanks!</p>
