Code Sample, a copy-pastable example

# Your code here
>>> pd.__version__
'1.1.0.dev0+1655.g1132aba3e'

pytest pandas/tests/io/test_clipboard.py

Problem description

Final three tests fail. Looks like the test is designed for Windows, I'm running a Mac. The test references PR#25040

EDIT: Just realized I'm actually running it in a Docker container. From Pyperclip documentation, looks like I need either gtk or PyQt4 (for Linux) or pbcopy and pbpaste (for Mac) installed. I suppose that should be included as a dependency in the Dockerfile?
