Hi,  
I'm trying to upgrade a fresh copy of NR on a Raspberry Pi-Zero-W.

My first step is trying to get npm (v1.4.21) upgraded to the latest version (v6.4.1 ????).

When I use...  
npm install -g npm@next  
I get loads of error messages.

Any suggestions on what I'm doing wrong ???

Have you used the usual upgrade script? That would be the recommended way to get node/npm up to date.

Could you give me a link to the script?

I tried...

sudo npm install -g --unsafe-perm node-red@next

Thanks guys.

The usual upgrade script got me to v0.19.5.

Now I'm going to upgrade to v0.20.0

Thanks for all your help.
