      throw er; // Unhandled 'error' event
      ^

For some reason the directory contains only the following files:

alex:~$ ls -a /Users/alex/.nvm/versions/node/v8.1.1/lib/node_modules/generator-d3-quickstart/generators/app/templates
.		.npmignore	gulpfile.js	js
..		css		index.html	package.json

I was able to workaround the issue by manually adding a .gitignore file to the directory myself... but I'm not sure why it wasn't there to begin with.

confirmed. I have the same issue

Having the same issue now. The file is there in the master branch that I cloned (screenshot) but I think the npm package must be out of date because it's not in the package that got installed.
