This appears to be an llvmlite issue, not librosa. There are apparently no llvmlite wheels for your platform, so it’s trying to build from source. You don’t appear to have the LLVM development package installed, so it fails to build. Python packages cannot specify dependencies to ubuntu packages, so this is kind of unavoidable.

My guess is that you could fix this by apt-get installing llvm-dev and trying again.

lvm-dev did not work for me on ubuntu 16.04.

I don’t know if all the update-alternatives are necessary though
