【ts】vue-typescript-admin类型报错

1.Property ‘validate’ does not exist on type ‘Vue | Element | Vue[] | Element[]’.
Property ‘validate’ does not exist on type ‘Vue’.Vetur(2339)

方法一：

(this.$refs.dataForm as any).validate() //这样就不报错了

方法二：
先在js里头的前面引入element 的Form,再as Form

import {Form} from "element-ui";
(this.$refs.dataForm as Form).validate();

2.xxx does not exist on type ‘AxiosResponse’.Vetur(2339)

解决方案：
(1).新建axios.d.ts文件，如在该目录： src/types/axios/axios.d.ts
(2).axios.d.ts文件内容

import * as axios from 'axios'

declare module 'axios' {
  interface AxiosInstance {
    (config: AxiosRequestConfig): Promise
  }
}

(3).修改项目第一层目录下的tsconfig.json配置文件

{
  "compilerOptions": {
    "typeRoots": [
        "./node_modules/@types",
        "./src/types/",
    ]
  }
}

(4).关闭前端服务器，再重启vscode，试试效果，不报错了

3.Element implicitly has an ‘any’ type because expression of type ‘string’ can’t be used to index type

是在for in中使用报错的，

    for (let prop in data) {
		console.log(data[prop]);  //使用data[prop]报错
    }

解决方案：
对象声明时加个any, let data:any = {}
