The library "Pillow" is required by WeeWX. Normally, it is downloaded and installed automatically by pip, but it appears that pip cannot find a prebuilt Pillow library. This can be for a variety of reasons, but it's usually as simple as an outdated copy of pip. It can also be because you are running on an unusual operating system or hardware, but it appears that you are on a Raspberry Pi, which is very common. So, odds are the problem is just that your copy of pip is not up to date. For details, see the wiki article *Troubleshooting pip installs <https://github.com/weewx/weewx/wiki/pip-troubleshooting>*.
As suggested in the article, try updating pip # Activate your virtual environment: source /home/pi/weewx-venv/bin/activate # Update pip python3 -m pip install pip --upgrade # Now try installing Pillow: python3 -m pip install Pillow If that works, then proceed with installing weewx. -tk On Tue, Jan 16, 2024 at 4:28 AM Francesco Fasano <fvirgol...@gmail.com> wrote: > > Hi Gary, and thanks for the reply.
