Anybody know how to publish React APP to Github Pages?

I've been followed the tutorial oncreact-react-app, but it has missed the forth step to configurate the github page.

I've tried below:

1.set home page as the github's address

2.Set Github Page as:

But still, it is still the static path problem(404 issue).

I've read the github pages's and creat react app's docs.

Still can't make it.

Anybody can help?

Thanks a lot.
