photutils: Cannot `import photutils` in a Google Colab notebook

It does not appear to be possible to import photutils on the Google Colab platform!

I tried the following:

1. Browse to https://colab.research.google.com and click “New Python 3 Notebook”
2. Runtime > Reset all runtimes (just in case)
3. Execute !pip install photutils (this works fine)
4. Execute import photutils

Step 4 yields the following exception:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-2-e3d8b5fe96af> in <module>()
----> 1 import photutils

TypeError: "None" was not specified in the function signature. If it was meant to be part of "**kwargs" then set "arg_in_kwargs" to "True".
