build fail from source code (windows)

[yananlemon]

I am new to node and grid-apps, I try to build it from source code,env is as below:

1. windows 10
2. grid-apps-4.0.33
3. node version: v12.22.12,v13.14.0,v19.9.0,v22.13.1.

But when I execute npm install, they all fail with the following error message:

`grid-apps@4.0.31 preinstall

node bin/install-pre.js; npx webpack --config bin/webpack-three.js

node:internal/modules/cjs/loader:1093
throw err;
^

Any idea? Thanks.

I'm still trying to get the build to work on windows. it's a host of problems including script interpretation and sym link support (or lack thereof). I'm currently building the .exe's using electron builder on mac. wish I had a better answer.

I was able to get KM running from source on Windows by installing WSL Ubuntu, cloning the repo there. I used nvm to install / manage node versions, but you have other options for getting node into WSL. the Electron app will not build in WSL 1 because it requires all of the gui / x / whatever libraries, which are missing in WSL. but you can start KM in dev or prod mode with:

git checkout rel-4.1
npm run setup
npm run dev --or-- npm run prod

the Bambu integration code only runs in dev mode

It's possible the Electron app will run for you if you have WSL 2. I'm only able to run WSL 1 in my environment. To attempt to run the Electron app, after npm run setup, use the command:

npm run start

this is how I got builds to work under windows using PowerShell:

this command allows npm to run once it's installed:

Set-ExecutionPolicy Unrestricted -Scope CurrentUser

install git:

winget install --id Git.Git -e --source winget

install node / npm:

winget install Schniz.fnm

open new power shell to continue install:

fnm install 22
fnm env --use-on-cd --shell powershell | Out-String | Invoke-Expression
node -v # Should print "v22.14.0".
npm -v # Should print "10.9.2".

clone grid-apps repo:

git clone https://github.com/gridspace/grid-apps

build KM binary

npm run setup
npm run build-win

.exe will be deposited in the dist directory
