Are you trying to install the node-red grovepi node i.e. [node-red-contrib-grovepi](https://flows.nodered.org/node/node-red-contrib-grovepi)?

If so, and if you want to install it manually, you want to be in the .node-red sub directory. Try this:

```auto
cd $HOME/.node-red
npm install node-red-contrib-grovepi

```

Ther latest version of node-red is 3.0.0 beta 4  
What you have reported is probably the version of node.js.

Please copy the node-red startup log and paste it in a reply from when it starts to when it says it is ready.

Then run

```auto
cat /etc/os-release 

```

And paste the results in the reply

I would suggest you open an issue on the node’s [GitHub page](https://github.com/O-Hahn/node-red-contrib-grovepi/issues) but you should note that the node has not been updated in over 4 years
