Web data connector: Error while starting npm

I am trying to set up the Web data connector to connect tableau with one of the API. I am getting following error while starting npm. Here are the commands that we executed and part of error message.

C:\....\webdataconnector-2.1.0>npm install --production

C:\....\webdataconnector-2.1.0>npm start
