在vue.js应用中本地注册组件有问题。我正在尝试使用movieCard.vue内部的parent mainview.vue。将Everythig像Vue文档一样,但仍会遇到此错误:
[Vue warn]: Unknown custom element: <movie-card> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

这里是 moviecard.vue (子组件(的代码

export default {
name: "MovieCard",
props: ["movie-info"],
data() {
return {

import { mapState, mapActions, mapMutations } from 'vuex';
import InfiniteLoading from 'vue-infinite-loading';
import MovieCard from "./MovieCard"
console.log(MovieCard)
export default {
name: 'MainView',
components: {MovieCard},
data () {
return {
chosenCategory: 'popular'
}
},
computed: {
...mapState([
'movies'
])
},
methods: {
...mapActions([
"getNextPageByCategory",
'setCategory'
]),
async infiniteHandler($state) {
await this.getNextPageByCategory(this.chosenCategory);
$state.loaded();
console.log("yay");
},
...mapMutations([])
},
components: {
InfiniteLoading
}
}
</script>
另外,我已经注意到,如果我将相同的组件放入我的app.vue root组件中,它会按预期工作(就像其他任何子组件一样,这些子组件在app.vue中本地注册(例如mainview.vue.vue.vue((。
此外,我会说我正在使用vuex,并在我的应用程序中使用vuetify。
试图解决此问题数小时,但目前尚无结果...
预先感谢您的帮助!
尝试在MainView
中定义您的组件:
components: {
'movie-card': MovieCard
}
编辑:也许是因为您定义了两次组件
在OP问题中,他在MainView.vue
中两次定义components
的错误,因此后者components
覆盖了第一个,这是一个声明的movie-card
组件,因此只有
components: {
InfiniteLoading
}
是一天结束时有效的注册组件,
components: {MovieCard},
被覆盖
今天,我经历了同样的狗屎
Unknown custom element: <movie-card> - did you register the component correctly? For recursive components, make sure to provide the "name" option.
我的错误是i 错误地将components
一词误入为component
没有s
。因此,如果你们以后去看这种错误,那么您很有可能错误某物。
VUE错误提示也足够聪明,可以问我们did you register the component correctly?
,但我们假设我们做到了,但是请坚持,我们可能没有。
话虽如此,问题与
无关components: {
'movie-card': MovieCard
}
// the above is the same at the below in Vue
components: {
MovieCard
}
如果您阅读了Sovalina的答案,请注意答案是他的 edit
另一件事顺便说一句,我以为问题与recursive components
有关,所以我 made sure providing the "name" option
,但是正如您可以阅读的那样,它与"name" option
无关movie-card
不是递归组件。就我而言,我通过添加字符s
而不是任何name
。
