Error during npm installation

[duzenko]

I have installed the 32-bit version of GH 9.20 and registered C:\Program Files (x86)\gs\gs9.20\bin as GS4JS_HOME but the npm package fails to install, seemingly requiring the 64-bit files?

C:\dev\pss2-backend>npm i

> ghostscript4js@3.2.1 install C:\dev\pss2-backend\node_modules\ghostscript4js
> node-gyp rebuild
