I'm trying to install Apache Flink with either python3 -m pip install apache-flink or pip3 install apache-flink, but both fail with an exit code 1 error:

[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure
× Encountered error while trying to install package.
╰─> numpy
note: This is an issue with the package mentioned above, not pip.
The output is quite long so I won't post the whole thing here, but if there's something in particular I should be looking for in there, any suggestions are welcome.
I've also tried starting with numpy already installed in a hope that apache-flink would just use the installed version but that didn't help.
pip3 --version ->
pip 22.1.2 from /Users/sophier/Library/Python/3.8/lib/python/site-packages/pip (python 3.8)
I'm on the new mac with the M1 chip incase that could be a problem.
PyFlink on a M1 is not yet supported but will be from Flink 1.16 onwards, see https://issues.apache.org/jira/browse/FLINK-25188
