Placing module code in local modules folder doesn't appear to be located by Native IDE

Sat 2018.10.06

Recently installed the new IDE 0.70.4 and thought I'd give this another try, but now in a separate new folder in the root of the drive, to avoid folder inheritance issues.

I'm on the same laptop PC with no SD card feature, so am puzzled by yet a new error:

                                          ^
=undefined

Even more puzzling, I didn't create, nor is there when using the 'Projects' button,
a folder named 'node_modules/'

re #4: 'I have noted on startup of the ide that sometimes do you need set the project sandbox on startup'

Not had to do this after checking each time is still intact on IDE start.
