./setup.py error

[kerbroasted]

Hello,

When running ./setup.py from /offsecfw/enumeration I get the following error

Traceback (most recent call last):
File "./setup.py", line 11, in
installed_packages = pip.get_installed_distributions()
AttributeError: 'module' object has no attribute 'get_installed_distributions'

There is no requirements.txt file to install.

Please advise?
