在引用中,报错 "runtime-core.esm-bundler.js:221 Uncaught TypeError: Assignment to constant variable" 是因为在子组件代码中尝试对常量变量进行赋值。常量变量一旦被赋值,就不能再进行修改。这可能导致运行时错误。
在引用中,报错 "runtime-core.esm-bundler.js:6764 Uncaught ReferenceError: scope is not defined" 是因为在 Home.vue 文件的 Proxy.handleEdit 函数中引用了一个未定义的变量 scope。这可能是由于代码中的错误或缺失导致的。
在引用中,父组件代码中的 filterConfirm 函数对 params 进行了赋值操作。请确保 params 是一个可修改的对象,否则会出现类似的错误。
总结起来,以上报错 "runtime-core.esm-bundler.js:221 Uncaught TypeError: Assignment to constant variable" 可能是由于对常量变量进行赋值操作,而 "runtime-core.esm-bundler.js:6764 Uncaught ReferenceError: scope is not defined" 可能是由于引用了未定义的变量。请检查代码,确保变量的使用正确并且已经定义。

runtime-core.esm-bundler.js?d2dd:40 [Vue warn]: Property "$store" was accessed during render but is not defined on instance. at <App>
This warning message is related to the use of Vuex store in a Vue component. It indicates that the component is trying to access the `$store` property, but the store is not defined on the component instance.
To resolve this warning, make sure that you have properly installed Vuex and created a store instance, and then inject the store into your Vue app using the `store` option. For example, in your main.js file, you can create a store instance and inject it into the app:
```javascript
import Vue from 'vue'
import Vuex from 'vuex'
import App from './App.vue'
Vue.use(Vuex)
const store = new Vuex.Store({
// ...
})
new Vue({
store, // inject the store into the app
render: h => h(App)
}).$mount('#app')
```
Then, in your component, you can access the store using the `$store` property:
```vue
<template>
<div>
{{ $store.state.someState }}
</div>
</template>
<script>
export default {
// ...
}
</script>
```
vite项目报错:Uncaught ReferenceError: exports is not defined e-router.esm-bundler.js:2
这个错误通常发生在使用ES模块语法的代码中,但是没有正确的配置。在Vite项目中,可以通过在`vite.config.js`文件中设置`output.exports`为`auto`来解决此问题:
```javascript
// vite.config.js
export default {
build: {
target: 'es2015',
outDir: 'dist',
// 设置output.exports为auto
output: {
exports: 'auto'
}
}
}
```
如果你使用的是Vue 3,也可以在`package.json`文件中添加以下配置:
```json
{
"type": "module"
}
```
这将告诉Vite使用ES模块语法来解析代码。
