Electron - Cannot find module napi-v4/tfjs_binding.node napi-v4 INSTEAD of napi-v5

[Infinitay]

I am fairly new to node.js and Electron let alone tensorflow for js, so pardon my ignorance.

TensorFlow.js version

"@tensorflow/tfjs-node": "^1.5.1"

Browser version

I am using Electron and this is what is returned using process.versions

{
"node": "12.8.1",
"v8": "7.8.279.23-electron.0",
"uv": "1.30.1",
"zlib": "1.2.11",
"brotli": "1.0.7",
"ares": "1.15.0",
"modules": "75",
"nghttp2": "1.39.2",
"napi": "4",
"llhttp": "1.1.4",
"http_parser": "2.8.0",
"openssl": "1.1.0",
"icu": "64.2",
"unicode": "12.1",
"electron": "7.1.7",
"chrome": "78.0.3904.130"
}

It says I am using Node version 12, but I recently installed v13.5.0, so I don't know why it says v12.

Describe the problem or feature request

I am getting this error when I run my electron application: Uncaught Error: Cannot find module 'C:\Users\redacted\Documents\Code\NodeJS\Face-API\node_modules\@tensorflow\tfjs-node\lib\napi-v4\tfjs_binding.node'. This started happening when I updated my old project that I have linked towards the end, both local dependencies and global. I also updated my node,js to the latest version for what it's worth.

So it seems to be trying to look for NAPI 4, but when I look into /node_modules/@tensorflow/tfjs-node/, there is a folder called build-tmp-napi-v5. Furthermore, and more importantly, when I go into /lib/, I find another folder labeled napi-v5, but no napi-v4. I was looking at other issues such as #2558 and #2341. From what I gathered, I think I need to downgrade my Node version and perhaps tfjs as well. I haven't tried yet, but I will in an hour or so of this post and post a reply.

I got around to coming back to this issue in an attempt to further troubleshoot it. I took a look once more at #2341 and realized that I also was using a different node.js version that Electron was (compiled with?). As of Jan 4th 2020, the latest Electron version is 7.1.7 and it is using Node version 12.8.1, so I installed Node v12.8.1 and tried everything once more. Voila! Problem solved.

If anyone else is having this issue, make sure your installed node.js version is the same as the version of Electron you're using!

EDIT: Although I'm curious, could this error be mitigated either by tfjs OR electron?

Thanks so much for your tip! I have been struggling for days to get it to work. Your solution was exactly it.
