SyntaxError: Unexpected token [ - ionic

Question

I'm trying to start off my first ionic app; getting 'SyntaxError: Unexpected token [' on every ionic commands. Literally all ionic commands returning the same output.

$ ionic start test --v2

/Users/user/.nvm/versions/node/v4.1.1/lib/node_modules/ionic/dist/index.js:24
        const [xcode, iosDeploy, iosSim,] = yield Promise.all([

The solution is not to downgrade as suggested by the previously accepted answer, but to upgrade Node as suggested in this answer.

Ionic needs to run on Node > 6.

So I was solving it upgrading Node on my Mac using Brew like:

brew upgrade node
brew link --overwrite node

First one was upgrading Node. The second one was needed to overwrite other Node binaries I had.

Using Node 7 I was able to execute the ionic command.
