backend.ai 설치

안녕하세요. 좋은 강의 제공해주셔서 정말 감사합니다. 

다름이 아니라 백앤드 설치시, 

jinjeong-eun@jinjeong-eun-ui-MacBookPro ~ % pip install -U backend.ai-client==19.03.2

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

Defaulting to user installation because normal site-packages is not writeable

이런 과정이 반복이 되는데, 파이썬 설치부터 잘못 된 걸까요?
