ModuleNotFoundError: No module named 'pkg_resources'

[Floriszz]

I can't use ESPhome HomeAssistant add-in, while my RPi 3b, does not have enough memory.
I want to setup a Bluetooth-proxy. I can with the ready made package through https://esphome.io/projects/?type=bluetooth, but then I can't change any of the yaml config later on.
So I want to do it through the command line interface on Windows PC. This is working for Arduino framework.
But bluetooth_proxy requires esp-idf. I do read some requirements on https://esphome.github.io/esp-web-tools/ about "Preparing your firmware' with a version 4 or v3. But I don't understand what is meant with that.

the error I get is:

pip install setuptools should get you past that error.

pip install setuptools should get you past that error.

That seems to work for me, however that means that there's a missing dependency in some package - right?

[Floriszz]

@joachimtingvold , thank you.
That did it!
I saw same comments like mine on other boards and agree, that this is a dependency if you want to manually install the esp-idf platform.

Same issue on a macOS using esphome from homebrew, resolved following @joachimtingvold suggestion but used pip as module since it is not available as command in esphome venv:
