Object doesn't support property or method 'entries' - error in IE11
You can downgrade your react-scripts version. In your package.json , alter to "react-scripts": "3.2.0".
Take a look at https://github.com/facebook/create-react-app/issues/8405.
It seems to be an issue with react-scripts
version 3.3.0 and higher. You could find many issue reports in GitHub, for example: github.com/facebook/create-react-app/issues/8197, github.com/facebook/create-react-app/issues/8195.
It can still work with [email protected]
. You could try to revert back to 3.2.0 as a workaround. Please also remember to delete .cache
folder in node_modules
and delete IE browser cache then try again.
