Help building backend datasource (MQTT for streaming data)

Grafana
11

I installed Go first according to these instructions and I now have a Go folder in the usr/local folder and my version appears as 1.17:

root@Debian-Dell:~# export PATH=$PATH:/usr/local/go/bin
root@Debian-Dell:~# go version
go version go1.17 linux/amd64

Then I installed Mage according to these instructions and have a mage folder in the root directory:

And then did the following (which seemed successful since I did not see any error messages):

root@Debian-Dell:~# cd mage
root@Debian-Dell:~/mage# go run bootstrap.go
Running target: Install
exec: go env GOBIN
exec: go env GOPATH
exec: git rev-parse --short HEAD
exec: git describe --tags
exec: go build -o /root/go/bin/mage -ldflags=-X "github.com/magefile/mage/mage.timestamp=2021-08-31T13:22:33-04:00" -X "github.com/magefile/mage/mage.commitHash=4cf3cfc" -X "github.com/magefile/mage/mage.gitTag=v1.11.0-2-g4cf3cfc" github.com/magefile/mage

With Go and Mage apparently installed correctly, I tried yarn install (which gave me no errors, just like last time) and then yarn build, I got a little bit further, but still ended with the /bin/sh: 1: mage: not found

root@Debian-Dell:/var/lib/grafana/grafana-plugins/mqtt-datasource-main# yarn build
yarn run v1.22.11
