This short guide explains how to install Python version 3.7.0 on a Raspberry Pi running Raspbian.
First, get rid of old versions:
apt list –installed sudo apt-get autoremove python*
Ensure system is up to date:
sudo apt-get update
Install the dependencies needed for building the distribution:
build-essentialtk-devlibncurses5-devlibncursesw5-devlibreadline6-devlibdb5.3-devlibgdbm-devlibsqlite3-devlibssl-devlibbz2-devlibexpat1-devliblzma-devzlib1g-devlibffi-dev
sudo apt-get install -y build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev
Get the python src distribution:
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz tar xf Python-3.7.0.tar.xz cd Python-3.7.0
Configure and compile (this might take an awful lot of time, depdning on your Raspberry’s performances):
./configure –prefix=/usr/local/opt/python-3.7.0 make -j 4
Install:
sudo make altinstall
Make aliases and default version:
sudo ln -s /usr/local/opt/python-3.7.0/bin/pydoc3.7 /usr/bin/pydoc3.7 sudo ln -s /usr/local/opt/python-3.7.0/bin/python3.7 /usr/bin/python3.7 sudo ln -s /usr/local/opt/python-3.7.0/bin/python3.7m /usr/bin/python3.7m sudo ln -s /usr/local/opt/python-3.7.0/bin/pyvenv-3.7 /usr/bin/pyvenv-3.7 sudo ln -s /usr/local/opt/python-3.7.0/bin/pip3.7 /usr/bin/pip3.7 alias python=’/usr/bin/python3.7′ alias python3=’/usr/bin/python3.7′ ls /usr/bin/python* cd .. sudo rm -r Python-3.7.0 rm Python-3.7.0.tar.xz . ~/.bashrc
Check proper installation:
python -V
