Hi zouzou, 

 

Greetings from Syncfusion.  

 

We are unable to reproduce the problem at our end. We suspect that your application package.json is incorrectly mentioning the version for ej2-material-theme. Refer to the available versions of the ej2-material-theme. Moreover, Grid don’t have depend to ej2-material-them package directly. So we suggest to ensure the package.json file. 

 

https://www.npmjs.com/package/@syncfusion/ej2-material-theme 

 

Refer to the Grid documentation for installation.  

 

https://ej2.syncfusion.com/documentation/grid/getting-started/?no-cache=1 

 

If you are still facing the problem, please share the package.json file. 

 

Regards,  

Seeni Sakthi Kumar S
