Install failure ambiguous argument 'master': unknown revision or path not in the working tree.

[ACECEO]

I have an Ionic V1 cordova project to which I am trying to install this localforage-cordovasqlitedriver plugin and I get an error on install.

I get the same error installing via "ionic cordova plugin add https://github.com/litehelpers/Cordova-sqlite-storage.git" or simply "cordova plugin add https://github.com/litehelpers/Cordova-sqlite-storage.git"

Failed to fetch plugin https://github.com/litehelpers/Cordova-sqlite-storage.git via registry.
Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.
Error: npm: Command failed with exit code 1 Error output:
npm-debug.log

I've attached the npm debug log.

Any help would be appreciated.
