Using a fresh image of 2023-12-11-raspios-bookworm-arm64-lite.img.xz

Raspberry PI OS Lite 64 Bit Bookworm on a Raspberry PI 5

After connecting through ssh I ran the following commands:

sudo apt update sudo apt full-upgrade -y mkdir prg cd prg sudo apt install git -y git clone https://github.com/signag/raspi-cam-srv cd raspi-cam-srv python -m venv --system-site-packages .venv cd ~/prg/raspi-cam-srv source .venv/bin/activate pip install Flask==3.0.0

when I entered 'flask --app raspiCamSrv init-db' I received the error below.

Hi, it seems that the picamera2 library is not installed on your system or it is not reacheable.

Could you please look at the Picamera2 Manual in chapter 2. to verify that the package is installed.

Normally the picamera2 package is located at /usr/lib/python3/dist-packages/picamera2

If picamara2 is not on your system , chapter 2.2 instructs how to install it. Please note that a pip install is not recommended.

I just recognize that you made a 'lite' installation. Probably picamera2 is not included there.

If you have a chance, try a system setup with Raspberry Pi Imager version 1.8.4 or later.

Solution was to run the below command as mentioned in the picamera2 manual top of page 6. The below command will install picamera2 without the GUI dependencies.

sudo apt install -y python3-picamera2 --no-install-recommends

Thank You, Lance

Thanks for the info. I have adjusted the description for installation. Added step 8.
