Syntax Error: Error: No ESLint configuration found.

方法一：
1.全局安装 ESLint ：npm i eslint -g
2.生成配置文件：eslint --init
3.根据自己的项目需求进行设置：

√ How would you like to use ESLint? · problems
√ What type of modules does your project use? · esm
√ Which framework does your project use? · vue
√ Does your project use TypeScript? · No / Yes
√ Where does your code run? · browser
√ What format do you want your config file to be in? · JavaScript
The config that you've selected requires the following dependencies:

eslint-plugin-vue@latest
? Would you like to install them now with npm? » Yes

方法二：
1.在项目中安装 ESLint ：npm install eslint --save-dev
2.生成配置文件：./node_modules/.bin/eslint --init
3.初始化成功后，会在项目根目录生成一个 .eslintrc.js 文件，文件内容：

module.exports = {
    "env": {
        "browser": true,
        "es2021": true
    },
    "extends": [
        "eslint:recommended",
        "plugin:vue/essential"
    ],
    "parserOptions": {
        "ecmaVersion": 12,
        "sourceType": "module"
    },
    "plugins": [
        "vue"
    ],
    "rules": {
    }
};

Syntax Error: TypeError: eslint.CLIEngine is not a constructor

解决方法：打开package.json将以下代码删除重新运行（将项目停掉，重新npm run serve）

删除后本项目的eslint语法校验会失效，即可运行成功(需重新npm run serve)
