Can't build tfjs-node on Windows 10; module_name not defined in binding.gyp.

I’m unable to run tfjs-node. It reports a missing bindings file. I see the file in my project, but I haven’t found a way to include it (via import or require).

I’m not certain, but it looks like “module_name” is referenced without being defined in binding.gyp

Hope this helps.

Looks good! I manually copied the dll as mentioned in #4257, and tfjs-node now imports and runs correctly. Thanks!!

Hi, I am encountering the same problem. How did you copied the dll? I cannot find it anywhere.

Edit: Well, I just forced everything to look the same as it requires, like I see napi-v7 in my module and I created a soft link name napi-v8. After that, it seems like installed without a problem. In case anyone is facing the same issue and doesn’t known much about node.js just like me, here is the code in powershell.

npm install @tensorflow/tfjs-node --ignore-scripts #prevent downloaded files to be deleted on failed install
cd .\node_modules\@tensorflow\tfjs-node\lib\
sudo New-Item -Path .\napi-v8 -ItemType SymbolicLink -Value .\napi-v7
cd ..\..\..\..\
npm rebuild @tensorflow/tfjs-node --build-from-source

@joemullenix-ks Looks like your issue is related to this bug https://github.com/tensorflow/tfjs/issues/4257, basically the dll file is not copied properly, when the node version is > 14.x
