You have, mysteriously, a version of pip that is using f-strings, such as f"ERROR: {exc}", even though f-strings were not introduced until Python 3.6. Furthermore, recent versions of NumPy support Python 3.7 and above.
f"ERROR: {exc}"
Try installing a more recent version of Python3, activating a virtual environment, and installing with python3 -m pip install numpy.
python3 -m pip install numpy
Python 3.5 is also EOL as of 2020-09-30.
