Plugin add error

[serkanr]

I cant add plugin to Cordova. I am receiving such an error

(node:8672) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Failed to fetch plugin https://github.com/jaeger25/Html5Video.git via registry. Probably this is either a connection problem, or plugin spec is incorrect. Check your connection and plugin name/version/URL.
