Я пишу свой первый веб-сервер node (не стесняйтесь давать мне отзывы), который использует экспресс и gith для развертывания. Проблема в том, что я получаю следующую ошибку при развертывании, и если я запускаю script через pm2, процесс, казалось бы, удаляется. Есть идеи? script приведен ниже.
sudo node server.js
