title: Error while installing tesseract-ocr
body: <p>I want to use pytesseract for ocr. So installed it. But before that i needed to install tesseract-ocr. I am using windows 8.1. I opened the command line and ran the command pip install tesseract-ocr. The following lines are the results of that command. </p>
  
  <p>I am not able to understand whats happening here. How can I understand this and help me to successfully install tesseract on my pc?</p>
