Run the react-scenejs-timeline alone

[mhsprog]

Hi
I downloaded this project through this command:
git clone git@github.com:daybrush/scenejs-timeline.git
Successfully
I want to run the react-scenejs-timeline project under this folder : “scenejs-timeline\packages\react-scenejs-timeline”

by running these commands

1. npm install
2. npm start

but when run npm start
The following address opens in the browser
http://localhost:3000/daybrush/scenejs-timelin
And the below errors are shown in the browser console

Uncaught SyntaxError: Unexpected token '<' => bundle.js:1
Manifest: Line: 1, column: 1, Syntax error. => scenejs-timelin/manifest.json:1

What’s the problem?
