angular-seed project throws createServer(){} has no method 'json()'

I am finding this issue with the angular-seed project. This issue happens when I run `npm test'. This happens just after downloading the seed, without modifying any of its files. Here is the error I am getting:

var json = require('connect').json()
                              ^
TypeError: Object function createServer() {
  function app(req, res, next){ app.handle(req, res, next); }
  merge(app, proto);
  merge(app, EventEmitter.prototype);
  app.route = '/';
  app.stack = [];
  return app;
} has no method 'json'

I have seen some posts in StackOverflow like this one. I have reinstalled karma, karma-jasmine and karma-phantomjs-launcher. But did not help.

Any solution for this issue?

Upgrading the node.js resolved this issue. I was the node.js version ~0.10.
