Ubuntu에 Python 3.7 Install 하기

최근 Ubuntu는 Python을 3.8을 기본으로 해서 릴리즈 되고 있다.

그런데 문제는 Panda 나 Numpy등의 Dependencies가 3.7에 맞추어져 있어서

프로젝트 빌드가 안되는 경우가 많았다.

 

그래서 Python 3.7을 추가로 설치해 보겠다. 

- 원래는 3.8을 삭제하고 3.7을 default로 설치 하려고 했었는데.. 리눅스 몇번 날려먹고... 3.8쓸때는 이유가 있겠지..

인스톨 하는데 필요한 패키지를 설치해 준다.

- sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libsqlite3-dev libreadline-dev libffi-dev wget libbz2-dev

이걸 다 install 해줘야 할 꺼 같다.

ubuntu@master:~$ sudo apt-get install libffi-dev gcc zlib1g-dev

wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz
tar -xf Python-3.7.4.tgz
./configure --enable-optimizations

티스토리 문제인지 내문제인지 모르겠지만 Code 블럭 하단에 한글이 써지지 않는다.

상기 코드를 보면 알겠지만 3.7이 인스톨 되고 /usr/local/bin 하단으로 관련 command가 설치 된다.

python3.7 -m venv ~/.devops

라고 하는 Virtual 환경을 잡아 주고

source ~/.devops/bin/activate

하면 (.devops)라는 환경이 표시되는한은 python은 3.7이 된다.
