title: How to install xlrd in python3 library
body: <p>I am trying to install xlrd to read Excel files in python.</p>
  
  <p>I have tried this: pip install -U pip setuptools. My macOS Mojave 10.4.3 has Python 2.7 which is where the default install goes to. But I have also installed Python3.7. How do I get pip install to my 3.7 directory?</p>
