Failed at the angular-seed@0.0.0 postinstall scrip

Question

I am getting below exception when I run the command npm install from my project directory in webstorm IDE.

bower angular-route#~1.4.0      ENOGIT git is not installed or not in the PATH

npm ERR! Windows_NT 6.1.7601

I have already installed node js and installed bower using command npm install -g bower.

Please help me how to fix this issue?
