Install serialport@0.14.1 on RIO

I have not been able to install serialport on a RIO, I have tried with the current version and with the previous one
I had previously done it with some RiO without any problem

Looks like you are trying to install it from the command line.
Also looks like you are trying to install it as root, which is why you are getting a permissions issue.

We recommend that you install the version of any nodes you want via the pallet manager.

If you really want to install via command line, you need to be the user ‘dev’, not root.
sudo su dev

Thanks for your quick help, “sudo su dev” worked fine for me
