Anyleaf PH Probe Dependency Installation Issue

Mycodo has been awesome so far, but I am having an issue installing dependencies for my Anyleaf PH probe.

I think the issue is that I don’t have the correct version of python to install scipy. Any help with this would be much appreciated!

Yes, your python version is too old. Either update Python or install the latest version of your Linux distribution, which should have Python >= 3.8.

Hi Kyle I have a similar problem trying to install an Anyleaf PH probe, but went through the process of installing python 3.8 and ensuring it is set for default. I still get an error “could not build wheel for numpy which is required to installl pyprojects.toml- based projects” I can add the input device due to dependency requirement not met.

Are you using a recent and updated version of Raspberry Pi OS? If so, you should be using a compatible Python version. If your OS is an old version or you installed it a long time ago, it may have an old Python version. Installing the latest OS fresh on a new SD card can often alleviate issues with an old OS and old software versions that may linger.

Hi Kyle I have now done a complete reset on the os re-flashed Debian Buster 22-04-04 onto new SD card up dated. Re installed mycodo. I get the same error “could not build wheel for numpy which is required to install pyprojects.toml- based projects” when trying to install Any leaf PH probe.
