installing numba 0.48 will solve your problem

@lostanlen : I'm sorry but staying up to date with the last version of numba is my objective.

Is there a way to run librosa on the latest version of numba ?

If not, do you have a plan to patch librosa in the future ?

@alexandreCameron the problem is already fixed on the development branch. You can follow the directions in the readme for installing from github.

The 0.8 release will be out some time in the next few weeks.
