[yt-users] Issue with "yt serve command"

[k.grisdale at surrey.ac.uk]

Hi Matt,

Thanks for the quick reply and help. As I said I am very new to python and so am unsure how to apply the PR. Do I just go to the ext direct_repl.py file on my computer and make the same changes that you have made or do I need to do something different?

Thanks

Kearn
