проблема установки bratreader: управляйте “Python setup.py egg_info” отказавший с кодом ошибки 1 в/tmp/pip-n_qu_f2a-build/

Мне не удалось установить bratreader (https://github.com/clips/bratreader) различными способами:

giuliano@giuliano-VirtualBox:~/Documenti$ sudo -H pip install 
bratreader-master
Collecting bratreader-master
Could not find a version that satisfies the requirement bratreader-
master (from versions: )

bratreader-master.zip
