Unable to install llvmlite in pip on Apple Silicon Mac (M1)

I’m having problems installing llvmlite from pip on MacOS Big Sur. The installation breaks on this check: clang-9: error: invalid version number in 'MACOSX_DEPLOYMENT_TARGET=11'. I checked with clang --version and I actually have clang 12.0 installed right now, but I think llvmlite uses its own custom clang++ based on version 9. But surely there is a way to get it to compile on Big Sur/M1 hardware? I tried running pip with arch -x86_64 prefix but it didn’t make any difference. I also tried installing ==0.33 to try an older version but got the same error message.

Can anyone help me solve this problem?

I was able to install llvmlite with pipenv on an m1 with the following steps:

• install cmake
• arch -arm64 brew install llvm@11
• LLVM_CONFIG="/opt/homebrew/Cellar/llvm@11/11.1.0_2/bin/llvm-config" arch -arm64 pipenv install llvmlite

It’s important to:

• specify version 11 of llvm (brew install llvm will get you version 12, and llvmlite specifically calls this out as a compatibility error).
• make sure you’re installing both with the same arch.
• double-check that your LLVM_CONFIG value is correct for your system (homebrew has recently changed where it puts things).

@thatandromeda 's workaround worked for me but I had to update the config path with /11.1.0_3/ and use my homebrew installed python instead:

LLVM_CONFIG="/opt/homebrew/Cellar/llvm@11/11.1.0_3/bin/llvm-config" arch -arm64 python3 -m pip install llvmlite
