Problem with after update

After update with apt update and apt full-upgrade i cant start Node-red anymore, because of the problem in the picture:

i would be very thankful for your help

What OS and version, and hardware are you running on?

What do these commands show?

node  -v
which node
apt policy node

Edit: please copy/paste text, not screenshot.

I am using a Raspberry Pi 4 8GB with Respian

> pi@raspberrypi:~ $ node -v
> v14.20.0
> pi@raspberrypi:~ $ which node
> /home/pi/.nvm/versions/node/v14.20.0/bin/node
> pi@raspberrypi:~ $ apt policy node
> node:

That is a bad idea.

I suggest you fully remove nvm and delete the .nvm folder. Then install the latest node-red and a good version of nodejs using the recommended script for a pi.. I fully expect that to fix the problem.

If i uninstall nvm could this cause problems with Grafana and influxdb because they are currently working without problems?

is that enough?
rm -rf ~/.nvm
rm -rf ~/.npm
rm -rf ~/.bower

i also found the following command:

rm -rf $NVM_DIR ~/.npm ~/.bower
pi@raspberrypi:~ $ nodejs -v

I am not aware of either of those needing nvm. How did you install nvm initially? You should uninstall it in the same way (and delete the folders).

I don't know what that command does. It is not installed on any of my systems. The command to show the version of nodejs is
node -v

I used rm -rf ~/.nvm and the instructions from your link and it worked :slight_smile:
Big Thanks!

I don't think that has uninstalled nvm, you have just removed the local folders. Whether you will see problems in the future I don't know. Probably not, provided you don't ever run the nvm command.

Thanks for the notice and your quick support :slight_smile:
