title: AWS throws the following error: "bad interpreter: No such file or directory"
body: <p>I'm not aware of anything on my system having changed, but the <code>aws</code> CLI tool has stopped working.</p>
  <pre><code>$ aws-bash: /Users/user_name/Library/Python/3.7/bin/aws:/usr/local/opt/python/bin/
  python3.7: bad interpreter: No such file or directory
  </code></pre>
  <p>I've tried <code>brew reinstall awscli</code> which is suggested elsewhere, but with no luck.</p>
