Я хочу поместить свое рабочее приложение на Heroku. Приложение, использующее Django и чат на основе Twisted websockets. Я не знаю, что это хороший подход, но я установил twisted через heroku bash, но когда я хочу запустить свой chatserver.py У меня есть исключение, потому что для какого-то скрученного модуля требуется OpenSSL, который не установлен в моем env.

Итак, простой вопрос: как установить Twisted для работы с websocket на Heroku?

Обновление при запуске twistd -n -y chatserver.py:
