Error in angular after upgrade from angular 7 to angular 8

Question

I upgraded angular from angular 7.3.9 to angular 8 and the ng serve command is throwing the following errors: any help would be appreciated. The errors are like so:

ERROR in./node_modules/prosemirror-commands/dist/index.mjs 362:53-65 Can't import the named export 'AllSelection' from non EcmaScript module (only default export is available)

Answer 1

The issue was being caused by "@progress/kendo-angular-editor": "^0.10.3" which was installed in my project.

The temporary solution was to remove it and reinstall, because this package was using the package prosemirror-commands which had issues, as @progress/kendo-angular-editor and it works now. Below are the steps taken:

npm uninstall @progress/kendo-angular-editor npm install @progress/kendo-angular-editor
