Trying to make my own git repository available as a package

I have a forked copy of ng2-charts in github. I put in my package.json the following line

"ng2-charts": "git://github.com/atlantageek/ng2-charts.git#v1.5.1",

Now I am getting an error like so when I do npm install

└── ng2-charts-base@1.5.0 extraneous (git://github.com/atlantageek/ng2-charts.git#2915b7d46d583107be496af115dcdd2c2229faf9)

any suggestions?
