Unable to Install macOS with M1 CPU

[pqhf5kd]

macOS 11.4. python 3.9.6

I installed pipx through brew and then ran pipx ensurepath.

Then I tried to install pybricksdev:

PIPX_DEFAULT_PYTHON=python3.8 pipx install pybricksdev

pipx.util.PipxError: Default python interpreter 'python3.8' is invalid.

So I tried 3.9 because that's the version I have installed:

PIPX_DEFAULT_PYTHON=python3.9 pipx install pybricksdev

Fatal error from pip prevented installation. Full pip output in file:
    /Users/jakeedmonds/.local/pipx/logs/cmd_2021-07-22_06.23.56_pip_errors.log

pip seemed to fail to build package:
    pybricksdev

Some possibly relevant errors from pip install:
    ERROR: Cannot install pybricksdev==1.0.0a10 and pybricksdev==1.0.0a11 because these package versions have conflicting dependencies.
    ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies

Error installing pybricksdev.

Then I tried:

pipx install pybricksdev and I get the same error as PIPX_DEFAULT_PYTHON=python3.8 pipx install pybricksdev

I tried specifying 1.0.0a10 and 1.0.0a11 one at a time and neither worked.

pipx install pybricksdev==1.0.0a10

    aioserial<2.0.0,>=1.3.0

Some possibly relevant errors from pip install:

    ERROR: No matching distribution found for mpy-cross==1.14

Do you happen to have a new M1 (Arm) Mac?

That is why the mpy-cross package is not available.

Upstream issues:

• https://gitlab.com/alelec/mpy_cross/-/issues/10
• Support for Apple M1 arm64/aarch64 chips multiarch/crossbuild#51

The first link is to the source repository for the mpy-cross package if you want to try to hack around it and build it yourself.

pybricksdev has been working on M1 macs for some time now
