Installing Python 3.7.4 on Raspbian

Installing Python 3.7.4 on Raspbian =================================

As of July 2018, Raspbian does not yet include the latest Python release, Python 3.7.4. This means we will have to build it ourselves, and here is how to do it.

  1. Install the required build-tools (some might already be installed on your system).

    If one of the packages cannot be found, try a newer version number (e.g. libdb5.4-dev instead of libdb5.3-dev).

  2. Download and install Python 3.7.4. When downloading the source code, select the most recent release of Python, available on the official site. Adjust the file names accordingly.

  3. Optionally: Delete the source code and uninstall the previously installed packages. When uninstalling the packages, make sure you only remove those that were not previously installed on your system. Also, remember to adjust version numbers if necesarry.

or simply copy the setup.sh content to a file called setup.sh, do a chmod +x setup.sh and execute the script via sudo ./setup.sh

Afterwards, execute any of your scripts (yourscript.py is just a placeholder) using

This guide is pretty much taken from the following tutorial: https://liudr.wordpress.com/2016/02/04/install-python-on-raspberry-pi-or-debian/ and https://gist.github.com/BMeu/af107b1f3d7cf1a2507c9c6429367a3b

sudo apt-get update -y
sudo apt-get install 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 -y
wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tar.xz
tar xf Python-3.7.4.tar.xz
cd Python-3.7.4
./configure
make -j 4
sudo make altinstall
cd ..
sudo rm -r Python-3.4.0
rm Python-3.7.4.tar.xz

Hi,
Follow the entire procedure but when its ready seems that it always look for the directory where I put the files after download them.

xxx@raspberrypi:~ $ python 3.7 --version
python: can't open file '/home/xxx/3.7': [Errno 2] No such file or directory

It has created the folder in /usr/local/lib/python3.7 after installation

Thanks a lot!
