Installing the Latest Python 3.7 on Ubuntu 16.04 | 18.04 | Website for Students

Python 3.7 설치

기존에 설치 되어 있는 Python 삭제

$ sudo apt remove python3 python3.6 python3.6-minimal python3.6-dev python3-pip
$ sudo apt autoremove

Python을 설치하기 전에 Python을 빌드하는 데 필요한 필수 패키지를 설치

$ sudo apt update
$ sudo apt install -y --no-install-recommends libbluetooth-dev tk-dev uuid-dev wget ca-certificates gnupg2 dirmngr gcc build-essential wget zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev

Python 소스 다운로드

$ PYTHON_VERSION=3.7.7
$ wget "https://www.python.org/ftp/python/${PYTHON_VERSION%%[a-z]*}/Python-$PYTHON_VERSION.tar.xz"

Python 빌드

$ tar -xvf Python-$PYTHON_VERSION.tar.xz 
$ cd Python-$PYTHON_VERSION/
$ sudo ./configure --enable-loadable-sqlite-extensions \
  --enable-optimizations \
  --enable-option-checking=fatal \

Python build finished successfully!
The necessary bits to build these optional modules were not found:
_bz2                  _dbm                  _lzma              
_sqlite3                                                       
To find the necessary bits, look in setup.py in detect_modules() for the module's name.


The following modules found by detect_modules() in setup.py, have been
built by the Makefile instead, as configured by the Setup files:
_abc                  atexit                pwd
