  <p>I ran the installation using admin privileges as well but get the same error.</p>
  
  <p>I need to parse some rrd files using the rrdtool and create graphs but I just cannot install this archive using pip.</p>
  
  <p>I am a newbie with python so I am not sure how to go about this.</p>
  
  <p>I tried to install it using tar.gz file downloaded from <a href="https://pypi.python.org/pypi/python-rrdtool/1.4.7" rel="nofollow noreferrer">https://pypi.python.org/pypi/python-rrdtool/1.4.7</a> still got an error </p>
