Hi,

Last night update my Node red on Raspberry Pi3B, now it does not star up correctly.

Used - bash \<(curl -sL [https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered](https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered))

Not quite sure how you got into this situation, the upgrade should have coped with it I think, but as it says you need to rebuild the serial node. Probably easiest way is just to reinstall it.

```auto
cd ~/.node-red
npm install node-red-node-serialport

```

and restart node-red.

**[Edit]** Actually I see other nodes are in a similar situation, in which case easier to do

```auto
cd ~/.node-red
npm rebuild

```

I have attempted "npm rebuild" but it fails.

Do you use the below to upgrade, or are there a better way of doing it?

bash \<(curl -sL [https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered](https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered))

How do you expect us to know how to fix it if you don't give us any information.  
Copy/paste the full output from the rebuild here.

The script is the right way, but possibly something went wrong. I presume when it ran it ran right through without showing any errors.

You ran `npm rebuild` from the wrong directory. As with all non-global npm commands it must be run from ~/.node-red

The port in use error is because node-red is already running. Use `node-red-stop` and `node-red-start` to stop and start it.

Uninstall what?  
nodejs or the i2c node?  
To uninstall the node  
`npm remove node-red-contrib-i2c`  
from the .node-red folder

Thanks , but it seems it does not remove it - when I run npm rebuild afterwards it still seems to be there.

To save us all time let me explain what I did to analyse the latest problem (which was basically the same as I did to analyse the last one).  
First look at the end of the install log, there I saw that it was an npm module called ursa that won't build.  
I then used my favourite search engine and searched for  
npm ursa  
and looked for the npmjs hit which took me to [https://www.npmjs.com/package/ursa](https://www.npmjs.com/package/ursa)  
There I checked that you were using the latest version (0.9.4) which you are.  
I then followed the repository link on the right hand side which took me to the modules github page. There I clicked on Issues tab and looking at a few of those it rapidly becomes clear that this node also will not build on nodejs 12 and it seems that the node is no longer maintained.  
I don't know which node-red node uses this but you should be able to work that out by searching for all the places ursa appears in .node-red/package-lock.json

This led me to do a bit more googling and found that to determine which nodes depend on ursa you can run  
`npm ls ursa`

Thanks for your help - really appreciate it.

I decided to take a spare SD and download the latest version of OS and then Node-Red.(will dig a bit more on the old SD (OS and Node-red) and see if that can be fixed)

This is also not working at the moment so will need to dig and see what the issues are.

Running Node-RED install for user pi at /home/pi on raspbian

This can take 20-30 minutes on the slower Pi versions - please wait.
