"ej.web.all\index.d.ts" got many errors when build project

[Joe]

Hi,

I am using VS2017 Community and ASP.NET  web application (.NET framework ) + Web API + Angular + Syncfusion to develop a website.

Recently I got a list of JQuery error from "ej.web.all\index.d.ts",  any advice on what's wrong with my current settings would be appreciated.

Build:All declarations of 'JQuery' must have identical type parameters.

C:\Users\xxxx\documents\visual studio 2017\Projects\Angular2MVC\Angular2MVC\node_modules\@types\ej.web.all\index.d.ts Line: 69899

Hello,

I had the same problem as Joe and when I applied your advice that problems gone but now I have different problem:

ERROR in E:/Angular/syncfusion-ng/node_modules/@types/jquery/index.d.ts (7815,11): Interface 'JQueryDeferred<T>' cannot simultaneously extend types 'Deferred<T, any, any>' and 'JQueryPromise<T>'.

and many others which follow this problem but I believe that root of all others are in this line.

Can we have qiuck solution?

Best regards,

Djordje

Hi Djordje Radovanovic, 

We deeply regret for the inconvenience caused. 

We have analyzed the reported jQuery issue “Interface 'JQueryDeferred<T>' cannot simultaneously extend types 'Deferred<T, any, any>' and 'JQueryPromise<T>'.”  and found that the cause of issue is, typescript definition file ej.web.all is not compatible with latest version(3.2.12) of jQuery file. So for now we suggest you to install and use @types/jquery version 3.2.7.  

Also we will let you know once we fixed issue and refresh it in DefinitelyTyped repository. 

Run the below command to install typings file jquery. 

npm install --save-dev @types/jquery@3.2.7 

Please let us know if you need further assist on this.
