CircuitPython version

CircuitPython 7.2.5

Code/REPL

git clone https://github.com/adafruit/circuitpython.git
cd circuitpython/mpy-cross
make

Behavior

Traceback (most recent call last):
  File "../py/makeqstrdata.py", line 29, in <module>
    import huffman
ModuleNotFoundError: No module named 'huffman'
make: *** [build/genhdr/qstrdefs.enum.h] Error 1
make: *** Deleting file `build/genhdr/qstrdefs.enum.h'

Description

After cloning https://github.com/adafruit/circuitpython.git for use in building mpy-cross (per https://learn.adafruit.com/creating-and-sharing-a-circuitpython-library/creating-a-library#mpy-3106477-16), making mpy-cross exits with this error:

Traceback (most recent call last):
  File "../py/makeqstrdata.py", line 29, in <module>
    import huffman
ModuleNotFoundError: No module named 'huffman'
make: *** [build/genhdr/qstrdefs.enum.h] Error 1
make: *** Deleting file `build/genhdr/qstrdefs.enum.h'

The circuitpython/tools/huffman folder appears in the local cloned repo, but is empty.

Additional information

git submodule status includes this entry:

Please refer to https://learn.adafruit.com/building-circuitpython/build-circuitpython on how to build CircuitPython. In this case you are missing make fetch-submodules.

huffman is a Python module you need to install via pip3 install requirements-dev.txt. But @deshipu is right: you need to follow the recipe in https://learn.adafruit.com/building-circuitpython/build-circuitpython, as there are a number of steps to prepare your environment. The steps have changed over the years, including recently.

Hijacking this a little bit, we have tools/huffman as a git submodule but also list huffman in requirements-dev.txt. We should do one or the other, but not both...

Thank you. It’s difficult to find the correct cookbook to follow.
I previously reported the issue for the instruction in the library learning guide. I’ll refresh the learning guide issue with new info after the latest change and when I get it to work.
