Running the tests with gulp throws an error

[jonahx]

To reproduce:

1. Clone the repo
2. npm install inside the directory.
3. Run gulp, per the instructions in the README.

What happens?

The following error occurs:

~/Downloads/api-node (master) $ gulp

What should be done

1. Fix the error so the tests can be run
2. Add additional details and instructions to the README, which is pretty bare at the moment.
