Did it used to work? If so what happened that might have caused it?
First make a copy of the file .flows_raspberrypi.json.backup, it may be useful later. Note there is a leading dot on the name.
Next rename the flows file flows_raspberrypi.json and restart node red then it will start with an empty flow file. See if it is ok then. If it is ok then it is something in the flows file that is causing it. Copy the saved backup file back and rename it flows_raspberrypi.json. The backup file is the previous version of the file so should be it before your last edit. Restart node red again.

Hmm, odd. You could try renaming the .node-red directory. Then restart node-red. That should recreate the directory with no local nodes installed. Then try the install from the command line again.
You still haven't told us what happened that might have triggered this.
Is the pi otherwise behaving normally?

i have been using node-red for one year now, and haven't done nothing differently.
I just started to have this memory Leaks.

I have daily saved the flows and the flows_raspberrypi_cred.json.

Should I clean all the raspebrry SD and start with a clean sheet?

Just seen your post in the right directory. It seems you have not got access to some folders. Possibly you have been running node-red or npm with sudo, which can cause that. To fix it

cd ~/.node-red
sudo chown -R pi:pi .

That should change the ownership of everything in .node red back to being owned by pi.

So after running chown you still see the access permissions error?

But if you don't want to investigate further then as I suggested you can rename the .node-red directory and restart node-red and it will create a new directory with no local nodes installed.

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials

You should set your own key using the 'credentialSecret' option in

file using your chosen key the next time you deploy a change.

Please try and make it clear what you have done. Do you mean you renamed the .node-red directory?
Are you telling it to install the node or is it doing that by itself?

As per the readme for the node did you try a manual install with --unsafe-perm ?
