[Tutor] Problem compiling code from GitHub

[Dave Hill]

I now have 'odswriter' working, thank you.

I, eventually, uninstalled all versions of python and cleaned out as 
many references to python and odswriter as I could find. I then 
installed 3.7, and odswriter using

     $ cd odswriter
     $ python setup.py install

I guess that the first attempt at the latter steps was thwarted by some path problem re. Windows?
