I use “react-router-redux”: “^4.0.8”, same error. Change version to “react-router-redux”: “^5.0.0-alpha.9”, then it’s fine
Issue happened because I used
"react-router-redux": "^4.0.8",instead of"react-router-redux": "^5.0.0-alpha.9",. I wonder why create-react-app doesn’t warn about undefined imports
