This happens when trying to follow the instructions in the readme. Installed babel has version 6.22.1

$ yarn install

$ echo "import DockerCloud from '../src/dockercloud'
const dockerCloud = new DockerCloud('username', 'password')
await dockerCloud.connect()
const stack = await dockerCloud.findStackById('stackId')
" > test/playground.js

$ npm run dev

> dockercloud@0.2.3 dev /path/to/dockercloud
> babel-node ./test/playground.js --presets=es2015,stage-0
