Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.

the same error

[ferassaqqa]

Try to install the plugin using phonegap like this
phonegap plugin add https://github.com/alongubkin/phonertc.git

its worked for me

try with --nofetch flag to use the old cordova plugin registry:

cordova plugin add https://github.com/alongubkin/phonertc.git --nofetch

[timonsku]

I having the same issue constantly with Cordova 7. The --nofetch flag makes no difference.
This only ever happens with git repos as it tries to find the git url as a plugin name in the registry which obviously fails. The expected behaviour would be that it tries a git clone not a registry fetch.
