Failed to exec start script - EventEmitter.<anonymous> (/usr/local/lib/node_modules/npm/lib/utils/lifecycle.js:279:16)

I have installed node 8.10 and downgrade to npm 4 because i have error message with npm 5.

*******************************************************************************
ERROR: npm 5 is not supported yet


Then I use the command to downgrade npm
npm install -g npm@4.

So I create my projet

$>npm install -g create-react-native-app
$>create-react-native-app AwesomeProject
$>cd AwesomeProject
$>npm start


And then I have the following error message.

> AwesomeProject@0.1.0 start /private/var/root/AwesomeProject
> react-native-scripts start

09:42:16: Unable to start server
See https://git.io/v5vcn for more information, either install watchman or run the following snippet:
