Подробные сведения:

 $ python3 --version
Python 3.6.9
 

Как я могу это исправить?

Пожалуйста, не забудьте обновить свою установку python.

Для пакета ledgercomm требуется как минимум python 3.8, как видно на сайте пакета.

В противном случае он не может быть установлен и приведет к ошибке, с которой вы столкнулись.
