ERROR: Failed building wheel for llvmlite python 3.8.5

Hello,

Please I am trying to install numba within my docker container, which uses alpine 3.10 as base image. I get the following errors below:

Failed to build llvmlite
DEPRECATION: Could not build wheels for llvmlite which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.

Any help will be greatly appreciated please.

@braxtonmckee thanks for reporting this. I ran the Dockerfile locally to obtain the pip version number and received this:

Step 3/4 : RUN pip3 --version
 ---> Running in 1e9552ec8beb
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)

If you make the following changes to your Dockerfile, the install will likely work:

FROM ubuntu:18.04

RUN apt-get update && apt-get install -y python3  python3-dbg  python3-pip

RUN pip3 install -U pip

RUN pip3 install llvmlite==0.34.0

Closing this as the original issue seems to be resolved (manylinux2010 wheels not installable on Alpine Linux). @Odianosen25 if you have some help building yourself using the directions above, it would probably be best to start a thread on the Discourse first: https://numba.discourse.group/ - many thanks!
