这个错误是由于sass-loader的配置不正确导致的。具体而言,错误信息指出了sass-loader的options对象中包含了一个未知属性additionalData,这个属性不在API schema中定义,因此引起了ValidationError。
要解决这个问题,可以尝试在webpack配置中修改sass-loader的options,将additionalData属性改为prependData属性,并将sass的变量定义放在prependData中,例如:
```
// vue.config.js
module.exports = {
chainWebpack: config => {
config.module
.rule('scss')
.use('sass-loader')
.tap(options =>
Object.assign(options, {
prependData: `
@import "@/styles/variables.scss";
`
})
)
}
}
```
这里的变量定义文件路径为src/styles/variables.scss,你需要根据实际情况进行修改。
希望这个解决方案能够帮助你解决问题。如果还有其他问题,请随时提出。
怎么解决这段报错Invalid prop: type check failed for prop "isLikinged". Expected Boolean, got Number with value -1. found in ---> <LikingCom> at src/components/likingCom.vue <ArticleIndex> at src/views/article/articleView.vue <App> at src/App.vue在<template> <div> <van-button class="starbtn" :icon="isLikinged ? 'good-job' : 'good-job-o'" type="primary" @click="LikingFn" :loading="likingLoading" /> <!-- <van-icon color="#777" name="good-job-o" /> --> </div> </template> <script> import { likingGoApi, likingOutApi } from "@/api/article"; export default { model: { prop: "isLikinged", event: "isLikingFn", //子组件触发的事件 }, props: { isLikinged: Boolean, artId: [Number, String], //作者id }, data() { return { likingLoading: false, //收藏按钮的loading }; }, methods: { async LikingFn() { // 收藏/取消收藏文章的点击方法 try { this.likingLoading = true; if (this.isLikinged) { // 为true的时候取关 await likingOutApi(this.artId); this.$toast.success("点赞成功"); } else { // 走关注接口 await likingGoApi(this.artId); this.$toast.success("取消点赞"); } this.likingLoading = false; // 关注或未关注,都要修改按钮的视图状态 // props单向数据流,不能在子组件修改,子向父 // this.$emit("isFollowedFn"); //this.$emit触发input自定义事件 // this.$emit("input", !this.value); this.$emit("isLikingFn", !this.isLikinged); } catch (error) { console.log(error); } }, }, }; </script> <style scoped lang="less"> /deep/.starbtn { background: #fff; border: 0px; color: #3a3a3a; .van-icon-star-o { color: #3a3a3a; } .van-icon-star { color: #ff9912; } } </style>代码里
这个报错是因为父组件给子组件传入了一个名为 `isLikinged` 的 prop,但是该 prop 的类型应该是 Boolean 类型,而实际传入的是一个 Number 类型的值 `-1`。你需要在父组件中检查并修正传递给子组件的 `isLikinged` 值,确保其为 Boolean 类型。
如果你确认传递给子组件 `LikingCom` 的 `isLikinged` 值是正确的,那么你可能需要检查子组件 `LikingCom` 中的代码,确保它正确处理了 `isLikinged` prop 的类型。你可以在子组件的 `props` 中指定 `isLikinged` 为 Boolean 类型,这样就可以在子组件中强制转换类型了。例如:
```js
props: {
isLikinged: {
type: Boolean,
default: false,
required: true,
},
},
```
这样在子组件中使用 `isLikinged` 属性时,就会被强制转换成 Boolean 类型,避免了类型错误的问题。
