Running ./owtf.py from the owtf directory and this is the error I am getting

Traceback (most recent call last):
File "./owtf.py", line 14, in
verify_dependencies(os.path.dirname(os.path.abspath(sys.argv[0])) or '.')
File "/root/owtf/framework/dependency_check.py", line 40, in verify_dependencies
owtf_libraries = [req.req.project_name for req in owtf_reqs]
AttributeError: 'Requirement' object has no attribute 'project_name'

I am running it out of VMware Fusion.
