TypeError: 'type' object is not subscriptable

[iDoka]

Приветствую!
В первую очередь спасибо за разработку.

Мой сетап:
OS: CentOS 7 64bit
Python 3.6.8

Пытаюсь запустить на последнем коммите из ветки мастер:

$ python3 -m poptimizer
Traceback (most recent call last):

pytest жалуется на аналогичную проблему:

Я что-то делаю не так или есть какой-то более стабильно работающий коммит?

У вас старая версия Python. В коде активно используются type hinting из версии 3.9

[keepitsimple]

@WLM1ke чтобы такой проблемы не возникало в будущем я добавил конфиг файл для poetry (https://python-poetry.org/). Poetry простой и очень удобный менеджер пакетов для проекта - это аналог npm / yarn в JS / TypeScript проектах. Он стал очень популярным в последнее время.

Если мой Pull Request будет принят, я сделаю еще один PR для Readme с описанием как разворачивать проект используя poetry.
