  • does such an old version of node understand `async` without some sort of command line option, perhaps? – Jaromanda X Jun 16 '18 at 02:07

    async/await didn't appear in node until 7.5 - so, I think you'll need some sort of transpilier ... or a current version of node - any reason you don't at least use node 8.x? – Jaromanda X Jun 16 '18 at 02:10
  • This answer might help with setting up babel with node v6 https://stackoverflow.com/questions/42299393/using-async-await-in-node-6-with-babel/42300449 – Brett Commandeur Jun 16 '18 at 02:12

Updating your node version to the LTS edition will resolve your issue.
