title: How to downgrade python version from 3.8 to 3.7 (mac)
body: <p>I'm using Python &amp; okta-aws tools and in order to fetch correct credentials on aws I need to run okta-aws init. But got an error message of <code>Could not read roles from Okta</code> and the system prompted that<code>&quot;Your Pipfile requires python_version 3.7, but you are using 3.8.3 (/usr/local/Cellar/o/1.1.4/l/.venv/bin/python)</code>.</p>
  <p>I've tried to search all the Pipfiles on the mac and it seems that the Pipflie under my <code>~/Pipfile</code> and <code>/usr/local/Cellar/python@3.8/3.8.3_2/libexec/bin/Pipfile</code> all have the same python version of 3.8, while the Pipfile under my  <code>/usr/local/Cellar/okta-aws-tools/1.1.4/libexec/Pipfile</code> has <code>required python_version = 3.7</code>.</p>
  <p>I've been struggling with this for a while and really not sure how I can fix this.</p>
