I have been using the package @material-extended/mde for implementing the popover with dynamic html content. But somehow I am getting error 

error TS1086: An accessor cannot be declared in an ambient context.

Now I have serched the issue over here that it's happening because the versioning with Typescript. I have tried upgrading @angular/cli, typescript, @angular/animations but that din't work for me. My package.json is as follow : 

{
  "name": "demo",
  "version": "0.0.0",
  "scripts": {

  }
}

Is there anything that I can do here to solve the issue ?

  • @PraveenSoni I saw ach and every possible options but it is not working – The Hungry Dictator Mar 05 '20 at 09:03
  • Same problem, using same version of typescript. I'm guessing this is a typescript compatibility issue with mde-popover. In the example from the github, typescript 3.1.1 is used – spencer Mar 19 '20 at 15:44
  • If you're using angular material, just use this, the end result is about the same and it only uses native angular material components https://stackblitz.com/edit/angular2-material-popover?file=main.ts – spencer Mar 19 '20 at 15:53
