I am trying to run my application in Visual studio 2017 and I keep getting the error:

 "Error TS2440  (TS) Import declaration conflicts with local declaration of 'PluginConfig'"

I tried downgrading my typescript, but the error is not going away. Below is my package.json file:

I tried opening the application in both Visual studio 2017 and 2019 and I getting the same error in both versions of Visual studio. I also tried to change the typescript version in Visual studio itself, but that didnt work either. Below is the screen shot from Visual studio Typescript version:

any help in resolving this error will be greatly appreciated.

Apparently this is an issue with the latest version[s] of Typescript greater than 3.6.4. As far as I can tell, there has been no fix for it in 3.7 or 3.8 which is the version I am on.

you can add the following to your tsconfig.json at your root folder to silence the error:

"compilerOptions": {
   ...,
   "skipLibCheck": true
}

Just ran into this with VSCode and Angular 9. Seems the issue was with VSCode's auto-import of EventEmitter from Protractor rather than @angular/core. Was wondering why VSCode was complaining that EventEmitter didn't have the subscribe() method available.

import { EventEmitter } from 'protractor';

should be import { EventEmitter } from '@angular/core';

Changed the import and all is well.
