After ejecting, there is an error says 'No PostCSS Config found'

I want to change the port, but can't figure out the right way.
so i ran the eject command, removed the react-app-styleguidist package and installed react-styleguidist instead. And here comes the error.

ERROR in ./~/css-loader?importLoaders=1!./~/postcss-loader!./src/index.css

Seems like recent updates in create-react-app had caused this.

Could you tell me version of react-scripts and react-styleguidist that you have?

in my package.json

"react-scripts": "0.9.5"
"react-styleguidist": "^4.6.3"
