title: cqlsh will not run on OS X
body: <p>I installed Cassandra on Big Sur 11.4 using homebrew, and when I tried to run cqlsh, I received this error.</p>
  <pre><code>isaackim@Isaacs-MacBook-Pro bin % cqlsh

  <p>I previously had Anaconda3 installed, and received the same error (the only difference was the path to cqlsh.py). I thought it might be an issue with Anaconda so I uninstalled Anaconda entirely, then I reinstalled Cassandra using homebrew.</p>
  <p>I would appreciate any and all suggestions. Thanks in advance.</p>
