Is it possible to use the already existing crypto-js of Node-Red to use it inside the Function-node?
Inside a for-loop I want to check if a part of a package is altered compared to my context-database. If so, I want to update that part. Because it happens inside a for-loop and only checks parts of an array, I want to use it inside my function-node and not outside with an external node.
If you are using newer version of node-red, you can import the crypto library on the function node setup tab...

I have updated it, but I can't get the node version to update as well. I run Node-Red on a raspberry pi and use the script from the website to update Node-Red. But with --node14 I still get version 12.
did you run the command correctly? ...
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --node14
Do you have n or nvm installed? These are often a cause of installation issues.
Not that I know of.
Version Node.js: v12.22.7
Version Npm: 6.14.15
what do you get if you enter the following in the terminal...
which n
which nvm
Also, try running this script once more (as I wrote it above) and capture the output and log file - paste into reply as text (press the code </> button then paste log/output between the backticks)
For which n and which nvm I got nothing.
No response just this:
pi@raspberrypi:~ $ which n
pi@raspberrypi:~ $ which nvm
pi@raspberrypi:~ $
I tried to add the log by pressing </> but the size exceeded the limit.
The log:
install log.log (74.3 KB)
Ok, good.
I think your system needs updating. Can you do sudo apt-get update then sudo apt-get upgrade
Then remove node sudo apt-get purge nodejs
After that, run sudo apt autoremove then sudo apt autoclean to clean up any install files
Then try the script again as I posted above.
Please include a copy of the terminal this time.
