使用Ant Design of Vue前端框架编写项目过程中遇到的问题汇总

问题1：main.js?56d7:27 Uncaught ReferenceError: Antd is not defined

*解决办法
在package.json文件中，添加babel配置，其中"libraryName"的值必须与main.js中的Antd一致。

main.js

import Vue from 'vue'
import Antd from 'ant-design-vue'
import 'ant-design-vue/dist/antd.css'
//导入app根组件
import App from './App'

Vue.use(Antd);
Vue.config.productionTip = false;

new Vue({
  render: h => h(App),
}).$mount('#app');

package.json

{
  "name": "antd-demo",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },
  "dependencies": {
    "ant-design-vue": "^1.4.10",
    "axios": "^0.19.2",
    "core-js": "^3.4.4",
    "vue": "^2.6.10"
  },
  "devDependencies": {

    "@vue/cli-plugin-eslint": "^4.1.0",
    "@vue/cli-service": "^4.1.0",
    "babel-eslint": "^10.0.3",

    "root": true,
    "env": {
      "node": true
    },
    "extends": [
      "plugin:vue/essential",
      "eslint:recommended"
    ],
    "rules": {
      "no-console": "off"
    },
    "parserOptions": {
      "parser": "babel-eslint"
    }
  },
  "browserslist": [
    "> 1%",
    "last 2 versions"
  ],
  
  //新添加的配置信息
  "babel": {
    "plugins": [
      [
        "import",
        {
          "libraryName": "Antd",
          "style": "true"
        }
      ]
    ]
  }
}

问题二：ERROR Error: Cannot find module ‘babel-plugin-import’ from ‘/Users/sundongping/IdeaProjects/umeapiplus’

问题产生原因：
未安装按需加载组件代码和样式的 babel 插件
解决办法
安装babel-plugin-import插件即可

npm i babel-plugin-import -D

问题三：warning.js?d96e:34 Warning: getFieldDecorator will override value, so please don’t set value directly and use setFieldsValue to set it.

问题产生原因：
在使用form组件时，我给每一个表单元素的value属性赋了初始值
解决办法
删除value属性，改用initialValue给每一项赋初始值

问题四：子组件向父组件传递引用参数（如数组）时，若父组件修改/删除该参数，子组件的数据也跟着一起改变

问题五：eslint:do not access object.prototype method ‘hasOwnProperty’ from target object no-prototype-builtins

问题产生原因：
我使用hasOwnProperty（）方法来判断某个键是否存在与Json对象中

# jsonRes是一个json对象，perror是键名
jsonRes.hasOwnProperty("perror")

解决办法
将上面的写法改为如下形式即可

# jsonRes是一个json对象，perror是键名
Object.prototype.hasOwnProperty.call(jsonRes, "perror")

问题六：Elements in iteration expect to have ‘v-bind:key’ directives vue/require-v-for-key
