Unknown custom element: <radio> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

使用表单中的radio组件时，报如下错误：Unknown custom element: - did you register the component correctly? For recursive components, make sure to provide the "name" option.
main.js中已经Vue.use(Element)了，但是感觉element-ui组件还是没有注入进来。
