Compiled on Ubuntu, it works.
I wanted to install a library uasyncio.

alex@ub2:~/micropython$ ./python -m upip install micropython-uasyncio
Installing to: /home/alex/.micropython/lib/
Installing micropython-uasyncio 3.0 from https://micropython.org/pi/uasyncio/uasyncio-3.0.tar.gz

alex@ub2:~$ ls ~/.micropython/lib/uasyncio
core.mpy  __init__.mpy  stream.mpy  task.mpy

Run program
I get an error.

Code: Select all

Traceback (most recent call last):
  File "/home/alex/PycharmProjects/pythonProject/main.py", line 16, in <module>
ValueError: incompatible .mpy file

Yes, I found that too. Looks like the upip mpy files haven't been regenerated.

I removed the ~/.micropython/lib/uasyncio folder, then copied uasyncio's source from the extmod tree:

Code: Select all

cp -r extmod/uasyncio ~/.micropython/lib

That seemed to allow the module to at least load:

Code: Select all

./micropython

or build micropython-dev for the unix port which includes uasyncio. (And complain on github so uasyncio gets finally merged in the non-dev unix port...)
