Я использую API, написанный на python и развернутый на сервере Eve. Далее я пытаюсь запустить Gunicorn (продакшн). Я выполнил команду gunicorn wsgi:app --preload -w 4 -b 0.0.0.0:7000, и она работает должным образом. Кроме того, когда мы запускаем эту команду, мы должны нажать Ctrl+s, чтобы рабочие начали запускать тот же код. Вопрос уже был задан рабочим, ожидающим неопределенно долгое время, чтобы начать работу, используя опцию предварительной загрузки. Однако я хотел убрать опцию предварительной нагрузки. Итак, когда я запускаю gunicorn wsgi:app -w 4 -b 0.0.0.0:7000, я получаю сообщение об ошибке.
Use a production WSGI server instead.

Более того, когда я удаляю `-w ', сервер запускается, как ожидалось, с одним рабочим.
Итак, как мне исправить эту ошибку с воркерами?
