For windows, since you are doing global -g install, try it from an elevated cmd prompt.

Right click cmd, run as administrator → npm install -g --unsafe-perm node-red

C:\Windows\System32>npm install -g --unsafe-perm node-red

something is wrong with your installation.

Re-install nodejs (I recommend V14 LTS) Node.js

5

nothing same probleme

6

what does where npm show?

Also,
Try deleting the npm folders...

  • C:\Users\94r4d0x\AppData\Roaming\npm-cache
  • C:\Users\94r4d0x\AppData\Roaming\npm\node_modules

then try again

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

There is not error - only warning & that is probably because you used nodejs 16 instead of v14 like i suggested. However, it not an issue.
