Hi,
I just want to update NodeRED to 4.0.5 from 3.0.2, so I launch the script on the [official site](https://nodered.org/docs/getting-started/local#upgrading-node-red) but something was wrong.
The script has updated Node from 16.x to 18.14.1 but hasn't update NodeRED and also now I can't run `node-red-start` because NodeRED try to start using node v12.22.12 and I don't know how to fix it!
[UPDATE]:
using `node-red --version` the correct version ov Node.js is selected and NodeRed start correctly, but with the old version.
Can someone help me!
Alan

I think you have `nvm` or `n` or some other node version manager installed. Uninstall that and all should be good (search internet for how to do that)

Thank you Steve,
So I need to uninstall n or nvm or NodeRED?

Yes, if you have them installed, and also you may need to delete local folders that they use. Work out what you have installed and then google for how to completely remove it.

Hi,
I don't know if it's true but seems that I not have installed either n or nvm:

What do the commands `node -v` and `which node` show?

Perhaps you have `volta` or `fnm` or `asdf` node version manager instead?
The reason I suspect you have a node version manager is your installation says Nord 18 was installed, but when you run node-red it reports version 12. This is very typical of a node version manager.

So, I'm not an expert of Linux OS so basically I don't know how to uninstall those softwares, if there is some correct procedure can you suggest a guide/tutorial/article for doing it in the correct way?

At some stage you have used nvm. Delete the `.nvm` folder and try those commands again.
**[Edit]** Then run the node red upgrade script again to correctly install a later version of nodejs.

Hi Colin,
Node-RED is sucesfully installed, but it isn't able to start yet:
```auto
It looks like serialport didn't install properly.
More information can be found here https://serialport.io/docs/guide-installation
The result of requiring the package is: undefined

is possible that is the MariaDB configuration that can have conflicts on it?

The UI dashboard is up and running, but the node-red console isn't able to load on the browser!

That means that probably node red was already running when you started it again. Stop node-red using
`node-red-stop`
then start it again using
`node-red-start`
If you still have problems then post the full output from `node-red-start`

So after running `node-red-stop` you still see the EADDRINUSE error? If so then run `node-red-stop` again then post the result of
`ps -aux |grep -i node`
and
`top`
If you are not seeing the EADDRINUSE error then please do as I asked and post the output from
`node-red-start` after running `node-red-stop`.

Basically the 10557 process was using the same address... I killed it and all it's working now!

If you do `sudo systemctl disable nodered` \* and reboot, what does `ps -ef | grep node-red | grep -v grep` show you?
Assuming it returns nothing, does `node-red-start` work?
`*` to make node-red start automatically [again] you would eventually need to run `sudo systemctl enable nodered`

Basically I think that the "node-red" service was activated by my call to `node-red --version`, so for now all it's ok... mabye when I have a moment (My nodered is going to menage many thinks so I can't just turn it off when I want) I can try to reboot RPI and see if all it's ok!

As you can see from the `top` output, node-red is hogging the processor, so something is wrong. The way to get round that is to do what @jbudd suggested, disabling the node red start on boot, then boot and run
`node-red --safe`
which will start the node-red editor without starting the flows. Then you can edit the flows (disabling tabs may be a good start to find where the loop is) and the flows will start when you deploy. You can check in `top` to see if it is ok, and if it is still hogging the processsor then reboot again and make some more edits.
