npm broken

Troubleshooting
1

Hi.

i was just upgrading node-red to the latest 1.2.9 (from .1.2.7) and ran the NPM command to do the update.

npm up -g --unsafe-perm node-red

but before it would do it NPM reported there was a minor update to do first and run this first

npm install -g npm@7.5.2

after doing that… if it then ran any NPM command it would now say NPM not found.

so i thought maybe somehow it has remove it self so did

apt-get install -y npm

but that now is just worse as it think it v5.8.0 and now it just crashes

looks like i accidently fixed it.

I fired up a VM copy dietpi so i can try to replicate it on there so as not to make the main system worse.

As the VM didnt have Node-Red on there i want to get that on it.

so did Dietpi-software Install 140

HOWEVER!!

Here is the accident.

  1. I ended up doing that command on the live box rather than the VM… i forgot which putty windows was the VM.
  2. software 140 is not node-red but Domoticz

so effectively i ended up installing Domoticz on to to the Main system… and funny enough whatever
the install did… NPM is now working again.

I can do npm - v and get back 7.5.2 fine.

So i now uninstalled Domoticz and everything is still all working.


so yeah all fine now. ta


fix was also to use

curl -qL https://www.npmjs.com/install.sh | sh

that’s indeed strange because Domoticz did not install anything related to npm.

The only thing I could imagine is probably a package update initiated by by dietpi-software as it is running apt update && apt upgrade in front of every software installation. Maybe it fixed your npm issue.
