Unable to `npm install` on Windows OS

Sorry.
It looks it does not work on the 8682404 either.
npm install does not end with errors, but it does not install modules/pgn-viewer/package.json. When I try to install it the same errors happen.

So I am trying to experiment over the fresh 1d51383 state...
When I remove the dependance line:

    "chessground": "mliebelt/Chessground",

The npm install works, but the build fails for

Module not found: Error: Can't resolve 'chessground' in 'D:\dev\PgnViewerJS-original\src'

[Bebul]

So, it looks like mliebelt/chessboard relevant issue, which is only fork of the original lichess chessboard.
I have tried to run yarn install here and it fails with the exactly the same reason:

'$npm_execpath' is not recognized as an internal or external command

When I replace the environment variable with

"prepare": "npm run compile", // instead of "prepare": "$npm_execpath run compile",

I am able to run yarn install and process demo.html.

I think, there are two possible ways to overcome this issue:

1. avoid using github repository as a library and deploy it into some @mliebelt/chessboard and use this one.
2. or try to make mliebelt/Chessboard cross platform
   • I have already tried to do it on the clone of your repository and I was able to build the chessboard
   • I will try to use it in the PgnViewerJS and if it works, I will try to pose a Pull Request

And here you are mliebelt/chessground#1

(I think, if the PR will be accepted (please, try it) then this issue can be closed.)

Ok, I have merged your pull request. I tried some months ago to upgrade Chessground to the newest version, but failed, and did not find out the reason for that. Perhaps I will try that again, to get rid of the necessity to build Chessground on my own. For the moment, you should be able to build pgn-viewer again.

It was first thing I tried too. Also failed.
I will try again.

For the moment, you should be able to build pgn-viewer again.

I was able to do so using my own build, forking yours, so I expect it really should work now.

Thank you 👍
