I separately installed @eeue56/bach so I'm not sure exactly what I'm missing.

[eeue56]

Can you share the code for the derw files?

[zainhoda]

Sure: Archive.zip

[eeue56]

Got it - so right now, the way you import packages is actually like:

import "../derw-packages/derw-lang/stdlib/src/Test" exposing (equals)

testMath: boolean -> void
testMath a? =
    equals 1 1

The path is relative to the file it's running from. Later on this will be simpler

[zainhoda]

Thank you! Is there a standard way to install derw packages?

[eeue56]

Yep, if you do derw install --name derw-lang/stdlib --version main it'll add that package with that git reference to the derw-package.json and grab it from github
