pytest Test Fails

[StevenBusuttil]

While following the steps for contributing here, I am getting the following error when running pytest Tests:

(venv) PS C:\Users\sbusuttil\pandas-bokeh\Pandas-Bokeh>  pytest Tests
Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 1072, in _find_spec
AttributeError: 'AssertionRewritingHook' object has no attribute 'find_spec'

During handling of the above exception, another exception occurred:
