Error installing llvmlite 0.34.0: FileNotFoundError: [Errno 2] No such file or directory: 'llvm-config': 'llvm-config'

I get this error installing llvmlite 0.34.0 in an AWS Linux AMI with python 3.6.

I understand the error but with version 0.33.0 this worked fine.

Complete output from command /usr/local/bin/python3.6 -u -c "import setuptools, tokenize;__file__='/tmp/pip-install-1x7b09lx/llvmlite/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" bdist_wheel -d /tmp/pip-wheel-14oz5zcs --python-tag cp36:

@LePoulpeOrange thanks for following up, it does indeed appear as though pip is unable to find the correct binary wheel from PyPi. Looking at the pip release notes for 19.0:

https://pip.pypa.io/en/stable/news/#id315

Implement manylinux2010 platform tag support. manylinux2010 is the successor to manylinux1. It allows carefully compiled > binary wheels to be installed on compatible Linux platforms. (#5008)

It appears that manylinux2010 support may not be available for the version of pip (18.1) that you are reporting. Would it be possible to upgrade the version of pip and try again?

I came across similar problem, and now put my solution. My environment is, ubuntu 16, python3.5, pip-18.0.

First, install llvm-8 sudo apt install llvm-8-dev

Then, relink ‘llvm-config’ sudo ln -s /usr/bin/llvm-config-8 /usr/bin/llvm-config

Finally, use pip install numba pip install numba --user

and, succeed.

Please check your version of ‘llvm-config’ llvm-config --version 8.0.0 (this is mine)
