I'm trying to install tfjs-node via npm install @tensorflow/tfjs-node on my mac.

Answer 1

OK, getting more information from https://github.com/nodejs/node-gyp it seems like node-gyp is not supporting Python version 3.xx is not supported.

So if you having the same error try to specify which Python version to use:

npm config set python /usr/bin/python
