Unable to start the flow

[ram1505]

Hi,
Each time I click deploy, node-red terminates. Here is the output:

Welcome to Node-RED
===================

28 May 13:59:52 - [info] Node-RED version: v0.17.5

It looks like serialport didn't compile properly. This is a common problem and its fix is well documented here https://github.com/voodootikigod/node-serialport#to-install
The result of requiring the package is:  undefined

What's the flow you are trying to deploy?

[ram1505]

The sample flow given in the flows.nodered page. I'm using raspberry pi.

Just tried the same.

Install Python and all dependencies on a fresh install.

I deployed the example flows as per instructed. If the folders didnt exist by chance, would the flows error out and crash Node-Red?

I have the same problem as ram1505. Actually adding any single node from machine learning palette to flow and deploying triggers the error for me

Same issue here, tried to use this nodes. Deployed them and boom. This error occours. Does anyone has an idea how to fix it?
