pybuilder: 'install_requires' must be a string or list of strings

This similar to Issue:123

error in project_name_here setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Invalid requirement, parse error at "'--index-'"

This error started happening when i updated my requirment.txt file to include a single dependency from my local PyPi

--index-url=http://123.123.0.123:8080/simple/ projectnamehere

This works fine for my pip installs when i do it directly. Should i be using a workaround and if should could you help me with what that might look like?
