Cannot install gulp-angular

Question

I am using gulp-angular for the first time, and am following this blog: http://www.angularonrails.com/how-to-wire-up-ruby-on-rails-and-angularjs-as-a-single-page-application-gulp-version/

When I run through the install questions, it just bombs out, on Karma.

I'm on ubuntu 14 in a Vagrant box, node v0.10.37, npm 2.7.5

Any pointers would be greatly appreciated.

Template processing error on file karma.conf.js

Some additional information, not really sure what to make of this, there is a _karma.conf.js file

EDIT

I have had to use sudo for all npm commands. Is this normal?

Answer 1

As per the github issue, deleting the reference to karma.conf.js from app/files.json did the job.

I guess there will be an official fix at some point.
