Material-UI Accordion (formerly ExpansionTable) component won't import
ExpansionPanel has been renamed to Accordion . With your error, it looks like you are using material-ui-core version 4.10.2 (or below).
Use material-ui-core version 4.11.0 or higher.
Install Material UI Core
npm i @material-ui/core
So , it will be @material-ui/core@4.11.0
Then, its working. Have fun!!
I had basically the same issue. Error was:
"Can't resolve '@material-ui/icons/ExpandMore'"
After installing the following:
"@material-ui/core": "^4.11.0","@material-ui/icons": "^4.9.1","avatar": "^0.1.0","clsx": "^1.1.1","jquery": "^3.5.1","material-ui": "^0.20.2","react": "^16.14.0","react-dom": "^16.14.0","react-ga": "^2.7.0","react-scripts": "1.0.17"I ran npm update and ALL WAS GOOD :)
