With gulp 4.0.2-3,

/home/pravi/forge/debian/git/js-team/node-babel/packages/babel-parser/src/x.js:
Unknown option: base.envName. Check out
http://babeljs.io/docs/usage/options/ for more information about options.

A common cause of this error is the presence of a configuration options
object without the corresponding preset name. Example:

Invalid:
  `{ presets: [{option: value}] }`
Valid:
  `{ presets: [['presetName', {option: value}]] }`

For more detailed information on preset configuration, please see
http://babeljs.io/docs/plugins/#pluginpresets-options.
