Jupyter notebook `pylab inline` gives `matplotlib` error

Previously, I was working on a Jupyter notebook project on a mac running Python 3.7.

Today, when I wanted to load the notebook's %pylab inline machinery, I received the error:

---------------------------------------------------------------------------

    277 
    278     if gui and gui != 'auto':

ModuleNotFoundError: No module named 'matplotlib'

I've tried looking for solutions online.

I have removed Python 3.6, reinstalled brew from scratch, reinstalled jupyter from scratch using the terminal but to no solution.

Is there a solution?

Don't use %pylab, it is deprecated. Use either:

%matplotlib inline

or %matplotlib notebook
