Promise rejections upon starting first exercise

[lxm7]

After running yarn start # or npm start on excercise-01, I receive warning:

UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): TypeError: "listener" argument must be a function
(node:21712) DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.

I did a brew update today and currently on node@7.7.2 and npm@4.1.2. Not sure if theres a breaking change there?

Im also getting, running npm i

node-pre-gyp ERR! Tried to download: https://fsevents-binaries.s3-us-west-2.amazonaws.com/v1.0.14/fse-v1.0.14-node-v51-darwin-x64.tar.gz
node-pre-gyp ERR! Pre-built binaries not found for fsevents@1.0.14 and node@7.7.2 (node-v51 ABI) (falling back to source compile with node-gyp)

Also tried other folders from repo also with same issue.

This is related to the very fresh bug regarding node@7.7.2 and create-react-app, more information can be found here: facebook/create-react-app#1776.

Solution: Either upgrade create-react-app to 0.9.5 or downgrade node to 7.7.1 or older.
