Hi.

Since I don't know your exact environment I cannot say what the problem is.
Depending on your environment you could try the following:

• upgrade setuptools + wheel ( pip install -U setuptools && pip install -U wheel)
• try pip's --egg option --> pip3 install --user --egg ./pybfd3
• do a local install via python3 ... or easy_install e.g. python3 setup.py install --user
