unable to find vcvarsall.bat

[nithya]

I am using a LULU package which was created 6 years ago. I am executing the package setup.py file in python version 3.6 and the unexpected error "Unable to find vcvarsall.bat". In that package they have used cython also, please assist me with resolving the error.

Is lulu a package format? What do one of it's packages look like?

Normally setup.py is used to install a program, and might not be needed to just run it.
vcvarsall.bat (I think) is normally used with VisualStudio to setup environment variables before visual studio's compiler starts, and thus might also be optional.
