Python環境を構築

ソースから構築

参考: https://gist.github.com/Sunlighter/87bbd2cd80971c7c0d4763ec1b5ea548

code: bash

$ wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz

$ tar -xJf Python-3.7.3.tar.xz

$ sudo yum install -y gcc bzip2-devel ncurses-devel gdbm-devel xz-devel sqlite-devel openssl-devel tk-devel uuid-devel readline-devel zlib-devel libffi-devel

$ mkdir python37

$ cd Python-3.7.3/

$ ./configure --prefix=/home/ec2-user/python37 --enable-shared --enable-optimizations

$ make

$ sudo make install

$ cd ..

$ echo 'export PATH="$HOME/python37/bin:$PATH"' >> .bash_profile

$ echo 'LD_LIBRARY_PATH="$HOME/python37/lib"' >> .bash_profile

$ echo 'alias python="python3"' >> .bash_profile

$ source .bash_profile

$ rm Python-3.7.3.tar.xz

$ rm -rf Python-3.7.3

pyenvで構築

Linuxシステムなら必要なものをインストール

code: bash

$ sudo yum -y update

$ sudo yum install git gcc zlib-devel bzip2 bzip2-devel readline readline-devel libffi-devel sqlite sqlite-devel openssl openssl-devel -y

pyenvをインストール

code: bash

$ git clone https://github.com/yyuu/pyenv.git ~/.pyenv

$ vi ~/.bash_profile

次のコードを追加

code: bash

export PYENV_ROOT="$HOME/.pyenv"

export PATH="$PYENV_ROOT/bin:$PATH"

eval "$(pyenv init -)"

再読み込み

code: bash

$ source .bash_profile

sudoでもuserのパス設定を引き継げるように設定

code: bash

$ sudo visudo

以下のように修正

code: sudoers

- Defaults secure_path = ...

+ # Defaults secure_path = ...

+ Defaults env_keep += "PATH"

+ Defaults env_keep += "PYENV_ROOT"

code: bash

$ sudo pyenv -v

pyenv 1.2.13

pythonをインストールし，適用

code: bash

$ sudo pyenv install 3.7.3

$ sudo pyenv global 3.7.3

$ sudo pyenv rehash

$ python --version

Python 3.7.3
