Unable to npm install on Windows OS

[Bebul]

It is a fresh problem.
After 1d51383 the npm install ends with errors, while when checkouting the previous commit 8682404 it works without any error.

The C:\WINDOWS\system32\cmd.exe /d /s /c $npm_execpath run compile cannot work on Windows OS, as there should be %npm_execpath% or something, and also this environment variable set. Maybe the package.json contains more than necessary?

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.

[Bebul]

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

[Bebul]

And here you are mliebelt/chessground#1

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

[mliebelt]

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 👍
