1. 필수 패키지 설치 1
apt-get install libssl-dev
apt-get install make build-essential libssl-dev zlib1g-dev libbz2-dev libsqlite3-dev
위와 같이 필요한 패키지를 설치하고 파이썬을 설치해야 정상 설치가 된다.
1-1. 필수 패키지 설치 2
sudo apt-get install libssl1.0
필자는 추가로 위 패키지도 설치해주었다.
위 패키지를 설치하지 않고 파이썬을 설치하고나서 pip 를 설치할 때 자꾸 아래와 같은 에러가 발생한다.
이것 때문에 2시간 삽질함, 아래는 삽질 기록이다.

위와 같은 에러를 치면 저 문법이 Python 3.5 와 호환되지 않아서
Python2.7 용 get-pip.py 를 설치해서 Python 3.5 를 설치하라고 나오는데, 그렇게 할 경우 또 아래와 같은 에러가 발생된다.
~$ python3.5 get-pip.py
DEPRECATION: Python 3.5 reached the end of its life on September 13th, 2020. Please upgrade your Python as Python 3.5 is no longer maintained. pip 21.0 will drop support for Python 3.5 in January 2021. pip 21.0 will remove support for this functionality.
Defaulting to user installation because normal site-packages is not writeable

2. 원하는 파이썬 버전의 다운로드 링크 복사하기
Welcome to Python.org
The official home of the Python Programming Language
www.python.org
3. 다운로드 및 압축풀기
$ wget <download link>
$ tar -zxvf Python-3.5.2.tgz
4. 설치하기
$ cd Python-3.5.2
$ ./configure
$ make
$ sudo make install
아래와 같이 뜨면 성공
Requirement already up-to-date: setuptools in /usr/local/lib/python3.5/site-packages/setuptools-33.1.1-py3.5.egg
Collecting pip
Installing collected packages: pip

만약에 python 3.5 의 pip 를 이용하여 패키지를 설치하려는데, 아래와 같은 에러가 난다면

아래와 같이 다시 python 3.5 버전에 맞게 다시 설치해주도록 하자
$ curl https://bootstrap.pypa.io/3.5/get-pip.py --output get-pip.py
$ python3 get-pip.py
