Pipenv stuck "⠋ Locking..." : <p>Why is my pipenv stuck in the "Locking..." stage when installing [numpy|opencv|pandas]? </p>

<p>When running <code>pipenv install pandas</code> or <code>pipenv update</code> it hangs for a really long time with a message and loading screen that says it's still locking. Why? What do I need to do?</p>
