Good thinking on the supervisor log:
Error: Cannot find module 'fs-extra'
This is the problem. This is a module that should have been installed already through the use of the
npm install command. It probably failed; I’m guessing you’re using NodeJS version > 8.x?
Try this, as
npm install fs-extra
If you get errors, those are the specific errors we want to see. It probably will tell us that this module, which is definitely necessary, isn’t compatible with … Node10 or Node12…or something to that effect. Which tells us also that your NodeJS version needs to be downgraded (removed and specifically installing Node8)
The steps in all the wikipages should definitely have installed Node8, so that’s another thing I’m interested in finding out–why any other version may have made it onto your system instead.
