Is that the original issue or why nodejs was apparently downgraded?

My request for the `apt-cache` command was related to why the script apparently downgraded nodejs.

The script wouldn't. If it finds anything more recent than 8.11.1 (the old debian apt install) it leaves it alone.

That's what I thought, but apparently (alledgedly?) something did.

On a side note I sometimes see odd things on the forum. Andrew's post showing the apt-cache results only just appeared, long after later messages. It has put it in the right place chronologically but it did not appear immediately. This has caused me confusion several times.

(Innocent bystander)

I post pictures with what I hope is needed. If they don't appear......

Could be the NBN and the great speed is (doesn't) have? (Aussie sarcasm)

`npm -g` === Global - needs sudo.

npm without `-g` === Local - should never use sudo.

You should never use `-g` unless you _know_ that you need it.

That will generally only be if you need a **system-wide** command from the installed package. With Node-RED, installing with `-g` gives you a global `node-red` command for example. You _can_ also install Node-RED locally but that is a different discussion.

With Node-RED, local installations of supporting packages (that provide nodes) should always happen in the `userDir` folder. This is normally `/home/pi/.node-red` AKA `~/.node-red`.

Yeah....

Ok.

I have updated 3 RPIs to 0.20.5

My main one is not playing the game.

Given they were all the same for install, that is a bit annoying.

And I did the same command from the same place in them all.

~/.node-red

And what happened (with -g it doesn't matter where you do it from)?

All the ones worked.

They installed the new NR and worked.

(Stopping/starting NR may have happened.)

This one...... The _pain in the a$$_ one..... Now just "hangs".
