Hello to everybody,

I would like to give me your help regarding one issue that I have.

I have installed the node red to my Mac and when I tried to start today the node-red I have the following error:

6 Apr 18:05:59 - [info] Starting flows

6 Apr 18:05:59 - [error] [serial out:14c18f45.aae2b9] missing serial config

6 Apr 18:05:59 - [info] Started flows

6 Apr 18:05:59 - [red] Uncaught Exception:

_**6 Apr 18:05:59 - Error: FATAL(Unknown Device): Unable to import automationhat python library**_

This problem probably occurred when I made the upgrade on the python.

**I tried to install it again but I have the following error:**

I'm wondering how I can delete the from the pallet the Automation hat ?

Thank you for your time.

Depending on the version of NR, you could start NR in `safe` mode  
`node-red --safe`  
and remove all occurances of the node and then in the palette manager, remove the node.
