Unable to "npm install @tensorflow/tfjs-node"

Question

I'm trying to install Node.js bindings for tensorflow.js. However, when I run "npm install @tensorflow/tfjs-node", I get the following output. Any help will be appreciated. Thank you!

D:\tensorflow.js>npm install @tensorflow/tfjs-node

> @tensorflow/[email protected] install D:\tensorflow.js\node_modules\@tensorflow\tfjs-node
> node-gyp rebuild

I may be wrong, but you're using Windows but as I can see on the npmjs.com – tfjs-node is available on Linux and macOS only.

TensorFlow.js for Node currently supports the following platforms:

1. Mac OS X CPU (10.12.6 Siera or higher)
2. Linux CPU (Ubuntu 16.04 or higher)
3. Linux GPU (Ubuntu 16.04 or higher and Cuda 9.0 w/ CUDNN v7) (see installation instructions)

Answer 2

Finally, i can run TensorFlow.js Node sample on Windows. Indeed, it runs on Ubuntu WSL (Windows Subsystem for Linux).

1. Enable WSL with powershell and install Ubuntu WSL from Microsoft Store.
2. Install several tool in Ubuntu WSL by apt-get, including NodeJS, Make, G++. Because the warning message is vague, I nearly gave up.
3. optional: Running Node.js on WSL from Visual Studio Code

I may missed some trivial steps.
