failed to resolve notebook boot environment

[floswald]

hi there
Im having issues with students being unable to run this notebook. I tried to keep to the structure in your MIT course notebooks, but it seems there is something failing when they want to create the new environment. Did I mess up the cell order? Here is the console output of the student in question:

Press Ctrl+C in this terminal to stop Pluto
┌ Error: Failed to resolve notebook boot environment

thanks for any help!

This issue is already fixed, they need to update Pluto.
