Hi Biagio ,
Thanks for contacting Syncfusion support.
We have checked the EJ2 VUE documentation samples, it’s working fine. If you are trying to create VUE grid as local project, then we suggest you to follow the below getting started link.
Note: The given error seems to ej2-vue-grids package not installed in your application. Please run the command: npm install @syncfusion/ej2-vue-grids --save
If you still face any issue, please the more error details we will check and provide better solution on this.
Regards,
Hariharan
