# Troubleshooting

This article provides solutions for issues you might encounter while working with the Kendo UI for Vue Charts.

## HammerJS Dependency

> Applies to @progress/kendo-vue-charts version 5.0.0 or older. Starting from version 5.1.0, HammerJS is no longer required.

When I try to use the Chart component, a Hammer.js-related error occurs

The `Chart` component requires Hammer.js to be installed as a [dependency](https://www.telerik.com/kendo-vue-ui/components/charts#dependencies). The error occurs because Hammer.js is not loaded.

**Solution**

Install the [Hammer.js](https://www.npmjs.com/package/hammerjs) package and import it by using the `import 'hammerjs';` command.
