You are using Python 2.7 and f-strings are available on Python >= 3.6.

Since the error comes from the package setuptools, you will need to downgrade setuptools to the last version compatible with Python 2.7, ie setuptools==44.1.1:

pip install -U "setuptools==44.1.1"

See the setuptools Pypi page for more info.
