Hi Darek,
We have validated your query and we would like to suggest you that please install and use the below npm 7 version to resolve the reported issue. Before reinstalling the dependent packages ensure that node_modules and package-lock files are deleted.
If you are trying to use our application in npm 7 version. Please run the below command while installing the Syncfusion package to resolve the reported issue. In latest npm version the peer dependencies have been installed automatically so it will block installations if an upstream dependency conflict is present that cannot be automatically resolved. For that we must run “--legacy-peer-deps” command to ignore peer dependencies entirely.
Please get back to us if you have any queries.
Regards,
Gokul
