Error installing Numba on OS X

I'm unable to install Numba (via pip) on my OS X system.

I'm using

  • Python: 2.7.11 (Homebrew)
  • pip: 8.1.1
  • setuptools: 20.6.7
  • OS X: 10.11.4 (x86_64)
  • Xcode: 7.3
  • Xcode CLT: 7.3.0.0.1.1457485338
  • Clang: 7.3 build 703

and have installed the prerequisites (I think) with

brew install llvm
git clone https://github.com/numba/llvmlite
cd llvmlite
LLVM_CONFIG=/usr/local/opt/llvm/bin/llvm-config  python setup.py install
cd ..
rm -rf llvmlite

and also tried

brew install llvm
brew link --force llvm  # later: brew unlink llvm
cd /usr/local/Cellar/llvm/X.X.X/include/llvm/Config/ # X.X.X = 3.6.2
ln -s llvm-config.h config.h

but I then

pip install numba

gives

  Failed building wheel for llvmlite
  Running setup.py clean for llvmlite
Successfully built numba
Failed to build llvmlite
Installing collected packages: llvmlite, numba
  Running setup.py install for llvmlite ...

I'm stumped about how to proceed (without Conda!) and wonder if there's some simple fix I'm missing.

How do I install Numba on my Mac?

The easiest way to install numba and get updates is by using Conda, a cross-platform package manager and software distribution maintained by Continuum Analytics. You can either use Anaconda to get the full stack in one download, or Miniconda which will install the minimum packages needed to get started.

Does Numba work on Mac?

numba-0.56. 2 has Python wheels for arm64 versions of macos, supporting Python versions 3.9. x and 3.10.

How do I fix legacy install failure?

Solve Error legacy-install-failure For Fbprophet This error occurs because you might not have installed dependencies for the wheel to be installed. You can solve this error by installing all the dependencies and then installing the 'fbprophet' using pip.

Here's what worked for me (with Homebrew Python on OS X 10.11.4):

brew install homebrew/versions/llvm37 --with-rtti
git clone https://github.com/numba/llvmlite
cd llvmlite
LLVM_CONFIG=/usr/local/Cellar/llvm37/3.7.1/bin/llvm-config-3.7 python setup.py install
LLVM_CONFIG=/usr/local/Cellar/llvm37/3.7.1/bin/llvm-config-3.7 pip install numba
rm -rf llvmlite
