改变

var sharedBlacklist = [/node_modules[/\]react[/\]dist[/\].*/,/website/node_modules/.*/,/heapCapture/bundle.js/,/.*/__tests__/.*/];

到

var sharedBlacklist = [/node_modules[/\]react[/\]dist[/\].*/,/website/node_modules/.*/,/heapCapture/bundle.js/,/.*/__tests__/.*/];

or

npm start

or

yarn start

It returns the following error message:
