const wait = (delay) => {
  return new Promise(resolve => setTimeout(resolve, delay));
}

async function tryWaitFunction () {
  console.log('スタート')
  await wait(1000);

nvm is not compatible with the npm config "prefix" option: currently set to "/usr/local/Cellar/nvm/0.31.2/versions/node/v7.0.0-nightly20161020d62e7bd1f9"
Run `npm config delete prefix` or `nvm use --delete-prefix v7.0.0-nightly20161020d62e7bd1f9` to unset it.
