Mycodo Install Failed

Mycodo
1

I have tried to re-install Mycodo on a Raspberry Pi 4B 64-bit (influx V2).

Unfortunately, I have encountered an error and I have failed to find a solution.

The install failed at:

pip._vendor.pyproject_hooks._impl.BackendUnavailable: Cannot import ‘setuptools.build_meta’

I cannot login to Mycodo.

Here is the install error:

How can I fix this?

What operating system are you using? It seems you’re using Python 3.13, which is very new, and likely the source of the incompatibility.

3

I followed the instructions on the Mycodo installation here. It appears that Raspberry Pi installs Python v3.13 by default.

How do I instruct Raspberry Pi to install the desired version of Python during the install?

That doesn’t answer what operating system you installed. Raspberry Pi OS Bookworm has Python 3.11. If you have 3.13, it indicates you didn’t install Bookworm that’s listed in the instructions.
