@PerspectivesLab thanks for reporting! I'm sorry to say that we don't currently develop on Windows machines so we have a blind spot in this regard, and it is difficult for us to diagnose the issues on our own. Another user reported a similar issue a little while back, and I responded here: #732 (comment)

If you or anyone else would be willing to help us with a patch to improve Windows support, we would be grateful 🙇

Hi @cdata ok ill try to fix that tomorow, thx !

[mister-elliott]

I was able to run the script on a second try on windows by setting an absolute path for fetch-samples:..
"update-screenshots": "node ./scripts/update-screenshots.js ./test/fidelity/config.json",
"fetch-samples": "e:/github/website/model-viewer/scripts/fetch-khronos-gltf-samples.sh",
"serve": "ws",
then npm install worked all the way through, with some report about npm audit, which I ignored.

after that, i ran

npm run build
and
npm run serve
and it is serving the samples correctly.

I assume some problem in npm in windows interpreting ./ directive
I ran my command prompt as administrator, probably don't need to.
suggest edit that one line in package.json for path to fetch-samples and try again.

maybe the docs could mention that windows is not supported much?

Thanks for diagnosing that @mister-elliott , I'm glad it was pretty straight forward.

And yah, we should mention that we don't have the ability to verify Windows compatibility for dev purposes.

I gitted everything to a ubuntu install on a dual boot laptop, then ran the npm commands, and everything works fine.

Hi,I get following error if i try to do 'npm i' in windows. Npm i was actually working fine before. Suddenly it stopped working, I am not able to understand the reason. Any help will be appreciated. Thanks in advance.

This is wen i do npm i through cmd-
'CALL "C:\Program Files\nodejs\node.exe" "C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js" prefix -g' is not recognized as an internal or external command,
operable program or batch file.

Also through vs code terminal it throws-
Program 'npm.cmd' failed to run: Access is deniedAt line:1 char:1

• npm i

At line:1 char:1

• npm i
