Missing kendo-react-popup
## Missing kendo-react-popup

On this page:

On this section: "Add a KendoReact Data Grid"

When I launch the app as usual:

yarn start

Then the browser page includes this error:

Compiled with problems:

ERROR in ./.yarn/__virtual__/@progress-kendo-react-data-tools-virtual-df92d36fcf/0/cache/ 19:0-55

Module not found: Error: @progress/kendo-react-data-tools tried to access @progress/kendo-react-buttons (a peer dependency) but it isn't provided by your application; this makes the require call ambiguous and unsound.

Required package: @progress/kendo-react-buttons

Ancestor breaking the chain: demo-react-kendo@workspace:.


The solution that works for me...

Add the package:

yarn add @progress/kendo-react-popup

Edit `src/App.js` and add this line:

import '@progress/kendo-react-popup';

Hello, Joel,

Thank you for the provided clarification and feedback. I tested the tutorial with the said command and Yarn 3.2.0 and the errors do reproduce. I will update the article and add the missing packages in order to avoid the error for future users.

As a small token of appreciation for bringing this issue to our attention, I have granted you some Telerik points.

Thanks Filip. Be sure you're using Yarn's current version which is Yarn 3.2.0.

The command you'll want is `yarn dlx create-react-app` which is *not* what's in your tutorial.

Hello, Joel,

Thank you for reaching out to us and for your feedback.

I followed the steps in the article and proceeded to the Add a KendoReact Grid step but the mentioned errors did not reproduce. When executing yarn start the app runs successfully and there are no errors present. 

Can you provide more information on the steps that you are executing in order to reproduce it?

Each component has a getting started page which lists the required dependencies:

We highly appreciate your feedback and if you have any other suggestions or questions, please do not hesitate to contact us again.

I hope this helps.
