Hi @HulioEglesias, thanks for reaching out!

Could you please provide additional info regarding your setup?

• Which Windows version are you one?
• Which Electron version are you using?
• Could you provide a little sample project / repo so I can get started quickly?

Best regards

Simon

Windows 10 version 1809(build 17763.1039)
Electron 7.1.11 (abi 75)
Node 12.15.0
Here is example: https://mega.nz/#!QbghBCTb!EavTn8q0IMl6_IhUo0T7QTrQGS0Ml-hu9_BdbKKrRl
For start, you need to have an electron and for start program use electron .

Would it be possible to provide the sample application in a repository?

@HulioEglesias Tried to use your download link, but it does not work.

} = require('@nut-tree/nut-js');
function createWindow () {
  // Create the browser window.
  const mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js')
    }

Hi @bluedarker,

nut.js uses node addons which would have to be re-built for usage with Electron, see Electron docs.

I did not yet spend time on this, but it would require additional build configs for multiple modules.
Can't promise when I'll find time to look into it, but I'll try to do so.

As always, contributions are very welcome! :)

Best regards

Hi @bluedarker and @HulioEglesias,

I published a next release of nut.js which comes with Electron compatible bindings.
Works well with electron-rebuild

Feel free to give it a try and let me know!

Sample:

npm i @nut-tree/nut-js@next
npm i -D electron-rebuild

npx electron-rebuild
npm start

[bluedarker]

@s1hofmann Thank you so much for you help and contribution, I will make a try and let you know the result within this week.

@s1hofmann
I have tried several times and the same problem with Electron quick start example still exists.

I have tried through different way, including electron-rebuild, electron-builder, node-gyp build and re-init after rm node_modules folder, same thing happened.

I know little about native module, it seems to me that rebuilding @nut-tree\libnut-win32\build\Release\libnut.node is needed. But there is no install.js provided in @nut-tree\libnut-win32.

Any of your replay is very much appreciated.

Could you provide me your ENV for my reference? Following is my ENV:

Windows 10 version 1809(build 17763.1158)
Electron 8.2.3
node 12.13.0

Hi @bluedarker,

I just set up a Windows VM and unfortunately, I can confirm your problem.
Sorry for the inconvenience, I only ran my test project on my MacBook and a Linux VM, where everything works fine after an electron-rebuild.

Although I'm having an assumption what might cause this problem, I'll have to investigate on it.

Would you mind opening a separate issue for Electron + Windows problems?

Thanks for your input!

Best regards

Simon

Edit: I guess my assumption was right: nodejs/node-addon-api#269 (comment)

[bluedarker]

Hi @s1hofmann,
Ok, I open this issues on #126
