A mini-howto for setting up a manual dev environment on the Raspberry Pi 5, figured I might save someone some time including myself in case I forget in the future.
- Install Raspberry Pi OS (64-bit) Lite per the instructions here.
At this time RPi OS uses Python 3.11 but HA Core needs at least version 3.12, so…
- Download and install Python 3.12.4 or later from source.
# Download source
$ wget https://www.python.org/ftp/python/3.12.4/Python-3.12.4.tgz
# Install the build tools
$ sudo apt update
$ sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev
# Configure, make and make install
# This will install Python at /usr/local/bin/python3.12
$ tar -xzvf Python-3.12.4.tgz
$ cd Python-3.12.4/
$ ./configure --enable-optimizations
$ sudo make altinstall
- Install HA manual development environment, following the instructions here). But before you get to this step:
# Install the requirements with a provided script named `setup` .
$ script/setup
Edit the setup script, modifying the following line.
python3 -m venv venv
to
/usr/local/bin/python3 -m venv venv
Then proceed with running the setup script. You should remove the above edit after the installation.
Of course this is basically a hack but since RPi OS will eventually use a more recent Python version its not worth modifying the script properly to handle this case at runtime.
