RuntimeError: <path> failed executing, please point LLVM_CONFIG to the path for llvm-config

Question

Trying to install llvmlite via pip by running

pip install llvmlite

constantly gives me this error:

    RuntimeError: <path> failed executing, please point LLVM_CONFIG to the path for llvm-config
    error: command '/Users/sfalk/miniconda3/envs/itranslate-asr-service/bin/python' failed with exit status 1
    ----------------------------------------

Now, I am on Python 3.5

$ python --version
Python 3.5.6 :: Anaconda, Inc.

And just running pip install llvmlite will give me this:

 RuntimeError: Building llvmlite requires LLVM 7.0.x, 7.1.x or 8.0.x, got '10.0.0'. Be sure to set LLVM_CONFIG to the right executable path.

I installed LLVM 8 via brew

brew install llvm@8

Setting LLVM_CONFIG to either does not work.

• /usr/local/opt/llvm@8/bin (were I assumed llvm-config to be), or
• /usr/local/opt/llvm@8/Toolchains/LLVM8.0.1.xctoolchain/usr/bin (where I actually found llvm-config to be)

And I keep getting some version of:

RuntimeError: /usr/local/opt/llvm@8/Toolchains/LLVM8.0.1.xctoolchain/usr/bin failed executing, please point LLVM_CONFIG to the path for llvm-config

What am I missing here?

And for those reviewing the post in search for a solution to installing numba, the version released on June 24, 2020 works: pip install numba==0.50.1

You will have to install the required llvm package using and link the executable config

sudo apt install llvm-**X**

and then

sudo pip3 install llvmlite 
cd /usr/bin
sudo ln -s llvm-config-**X** llvm-config

This fixed the llvm issue of installing librosa on my raspberry pi (aarch64)

Looks like there is an issue with latest version of llvmlite. Please consider using 0.31.0 version.

I was facing the same issue this didnt work

You will have to install the required llvm package using and link the executable config

sudo apt install llvm- X

and then

sudo pip3 install llvmlite cd /usr/bin sudo ln -s llvm-config- X llvm-config

didnt work for me.. but i did notice we had the same output error

RuntimeError: <path> failed executing, please point LLVM_CONFIG to the path for llvm-config

so.. logic kicked in.. why not point the LLVM_CONFIG to the proper llvm-config

simple fix

export LLVM_CONFIG=/usr/bin/llvm-config-10
