How to use yargs array syntax with gulp?

Question

Using array syntax of yargs with gulp throws errors. Here is my code:

var argv = require("yargs")
  .array("modules")
  .argv;

and using it like this:

gulp taskname --modules m1 m2
Task 'm2' is not in your gulpfile

How can I set an array using yargs in gulp?

Answer 1

I found a workaround for it:

gulp taskname --modules m1 --modules m2

Answer 2

Watch out! If you wan't to use required parameter via Gulp. In this case, yargs dosn't act like expected.
