See this post:&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/65889/nrfutil-modulenotfounderror-no-module-named-constants/286320#286320">https://devzone.nordicsemi.com/f/nordic-q-a/65889/nrfutil-modulenotfounderror-no-module-named-constants/286320#286320</a></p> <p>Try using python 3.8 or 3.7 instead.</p><div style="clear:both;"></div>
