Describe the expected behavior the command npm i @tensorflow/tfjs-node should succeed.

Standalone code to reproduce the issue Provide a reproducible test case that is the bare minimum necessary to generate the problem. If possible, please share a link to Colab/CodePen/any notebook.

I have used to following install command in a clean folder

npm i @tensorflow/tfjs-node

Other info / logs Include any logs or source code that would be helpful to diagnose the problem. If including tracebacks, please include the full traceback. Large logs and files should be attached. Not applicable - log reported above

To fix the issue (worked for me on Ubuntu 18)

sudo apt-get update
sudo apt-get install build-essential
npm i node-pre-gyp -g

(if your using tfjs-node-gpu)
npm rebuild @tensorflow/tfjs-node-gpu --build-from-source

(or if your using tfjs-node instead)
npm rebuild @tensorflow/tfjs-node --build-from-source

The other approach I have used was to reinstall npm doing sudo npm install npm@latest -g so I have

$ npm --version
6.14.8

and now it works! 💯

The problem now becomes th 2nd one, I have cited here
