ImportError: No module named enum
I ran into this same issue trying to install the dbf package in Python 2.7. The problem is that the enum package wasn't added to Python until version 3.4.
It has been backported to versions 3.3, 3.2, 3.1, 2.7, 2.6, 2.5, and 2.4, you just need the package from here:https://pypi.python.org/pypi/enum34#downloads
I ran into this issue with Python 3.6 and Python 3.7. The top answer (running pip install --upgrade pip enum34) did not solve the problem.
I don't know why, but the reason why this error happen is because enum.py was missing from .venv/myvenv/lib/python3.7/.
But the file was in /usr/lib/python3.7/.
Following this answer, I just created the symbolic link by myself :
ln -s /usr/lib/python3.7/enum.py .venv/myvenv/lib/python3.7/enum.py
