I came across an issue where I need to install a specific version of a plugin in Grafana, I tried command grafana-cli plugins install jdbranham-diagram-panel --version=1.6.1 which didn't work. I am trying to install jdbranham-diagram-panel plugin's 1.6.1 version in my system.
Following command should do the trick.
grafana-cli plugins install jdbranham-diagram-panel 1.6.1
In above command I needed to install plugin named jdbranham-diagram-panel with version 1.6.1 so we can use above command to do so.
Basically syntax of installing any plugin with specific version will become like:
grafana-cli plugins install plugin_name plugin_version
