Plugin unavailable

[HenrikRolandHansen]

Sorry if this is not the right place for this issue. But I'm not able to make the mqtt-datasource plugin working. after compile(yarn install and Yarn build) and setup the "allow_loading_unsigned_plugins = grafana-mqtt-datasource" in the ini file I get Plugin unavailable when saving "Save and test" in grafana.

I do have a problem with build that might create this problem, but lack of skills cant solve what's the issue. During compile I get error code 127

✔ Compiling...
/bin/sh: 1: mage: not found
error Command failed with exit code 127.

thanks in advance

looks like your build environment is missing mage, which handles the building of the backend. you can follow instructions here to get that on your build environment: https://magefile.org/

essentially:

git clone https://github.com/magefile/mage
cd mage
go run bootstrap.go 

you will need golang installed for that to work.

for a streaming backend datasource plugin (which this plugin is):
