I'm triyng to understand why those errors appear. A node-red installation works well and fast installing and removing nodes from pallette until you install node-red-contrib-modbus. Then package installations stuck for some time on every operation.

I'm also concerned about the modbus nodes not working completely well because of that.

What version of Node-RED and node.js are you using?

Thanks Knolleary.  
This is an embedded Victron Cerbo (PV device) that suits with node-red.  
As is, it doesn't let me install `build-essential` that usually fixes those errors in my other node-red machines.

```auto
# node -v
v14.17.4
# npm -v
6.14.14

```

Why not? No space? Errors occur? What errors?

It doesn't let me install anything that doesn't come from the Victron repos. The package manager also is locked down. In fact is opkg.

Maybe you could contact victron, perhaps they have an opkg or would generate a patch?

You could also look into cross compiling for the machines architecture (never done this for node bindings so you'd have to read up on this)
