There was a problem in the last step of installing the API

[coco-99-coco]

The error is displayed on the terminal as follows: class NumbaBuildExt(build_ext): TypeError: get_cmdclass() takes 0 positional arguments but 1 was given Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-yj45kxmu/numba/

I use Python 3.8 ,pip9.0.1,ubuntu18. How can I solve this problem?
