Установить путь к библиотеке для установки единорога с помощью pip на macOS (libunicorn.dylib отсутствует)

Question

Я хочу установить Python Unicorn на MacOS Mojave, используя python (2.7) и pip.

Я уже скомпилировал libunicorn.dylib из исходного кода, который можно увидеть ниже:

Nicolass-MacBook-Pro:Tools nlykkei$ sudo find / -iname libunicorn.dylib 2>/dev/null
/usr/local/lib/libunicorn.dylib

Когда я пытаюсь установить Python Unicorn, я получаю следующую ошибку, а именно, что libunicorn.dylib не может быть найден. Как сделать так, чтобы pip использовал библиотеки в /usr/local/lib?

Nicolass-MacBook-Pro:Tools nlykkei$ UNICORN_QEMU_FLAGS="--python=/opt/local/bin/python" pip install unicorn
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

Answer 1

Кажется, что модуль единорога в PyPI довольно старый - версия 1.0.1 была выпущена 31.05-2017, в то время как код в хранилище свежий.

Клонируйте репозиторий и установите с помощью команд:

cd bindings/python
sudo python setup.py install

Это создаст основную библиотеку C и привязки python.Смотрите инструкции на https://github.com/unicorn-engine/unicorn/tree/master/bindings/python
