Installation of midi-relay (as a service) on a RPi #16

Closed mark-epstein closed 3 years ago

mark-epstein commented 3 years ago 


Tried to do a manual install of Companion on my new rpi, got to some error message I couldn't understand and Google didn't help, so I started over with a CompanionPi image.  On my own, etc, I get it but Companion seems to be running OK.

Next I wanted to add midi-relay.  Installed node I think successfully, I get this:
```
    pi@raspberrypi:/usr/local/src/midi-relay/midi-relay-2.2.0 $ node --version
    v15.12.0

```
But if I try to run **sudo npm install -g pm2** I get this response:
```

I don't understand why these errors seem insistent that I'm running node v8.17.0 when node itself tells me I'm running 15.12.0.  Am I misinterpreting the messages?

Also my npm version is 7.6.3 (not 6.13.4)
And midi-relay runs under Node manually, (at least it appears to, I haven't tested any actual MIDI transport) but I'd like it to run as a service.

I feel like MY learning linux is like learning to ride a bicycle on the side of a motorcyle race track. When I do something wrong, I rarely know what I did. Same as when I do something right.

I don't know what I did but somehow the same command is no longer giving me those "notsup" warnings and everything is running. ¯\(ツ)/¯
