React Kendo UI TreeView 抛出“未定义剑道”

Question

我正在使用 Kendo UI 开发一个 React 项目。我按照Kendo UI TreeView的步骤操作

我已经安装了@progress/kendo-treeview-react-wrapper、@progress/kendo-ui，并使用import '@progress/kendo-theme-material/dist/all.css';将主题导入到我的项目中

当我使用 KendoUI 按钮时，一切正常，功能和主题是预期的，但使用时会抛出错误 TreeView

Uncaught ReferenceError: kendo is not defined
    at TreeView.componentDidMount (bundle.js:69556)
    at commitLifeCycles (bundle.js:12471)

有人可以帮忙吗？谢谢！

Kendo React 的说明是：

还有一步要做，我们需要明确导入@progress/kendo-ui：

import kendo from '@progress/kendo-ui';

Plunker Examples from KendoUI 帮助我弄清楚。
