You may use special comments to disable some warnings.
Use // eslint-disable-next-line to ignore the next line.
Use /* eslint-disable */ to ignore all warnings in a file.

解决办法1：

执行以下命令：

npm init -y

npm install eslint --save-dev

进入./node_modules/.bin/文件夹，执行以下命令：

cd ./node_modules/.bin/

eslint --init

在对话框中除了选择Vue.js，其它选项默认即可，如下所示：

? How would you like to use ESLint? To check syntax and find problems
? What type of modules does your project use? JavaScript modules (import/export)
? Which framework does your project use? Vue.js
? Where does your code run? (Press <space> to select, <a> to toggle all, <i> to invert selection)Browser
? What format do you want your config file to be in? JavaScript
Checking peerDependencies of eslint-config-eslint:recommended,plugin:vue/essential@latest
Local ESLint installation not found.
The config that you've selected requires the following dependencies:

eslint-plugin-vue@latest eslint-config-eslint:recommended,plugin:vue/essential@latest error@[object Object] eslint@latest
? Would you like to install them now with npm? Yes
Installing eslint-plugin-vue@latest, eslint-config-eslint:recommended,plugin:vue/essential@latest, error@[object Object], eslint@latest

Successfully created .eslintrc.js file in D:\study\vue\vue2\vuesaxvuejs-210\vuesaxvuejs-210\node_modules\.bin
ESLint was installed locally. We recommend using this local copy instead of your globally-installed copy.

把./node_modules/.bin/文件夹下面生成的.eslintrc.js文件，拷贝到项目根目录。

解决办法2：

首先，安装 ESLint。

$ npm i -g eslint

然后，安装 Airbnb 语法规则，以及 import、a11y、react 插件。

$ npm i -g eslint-config-airbnb
$ npm i -g eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react

最后，在项目的根目录下新建一个.eslintrc文件，配置 ESLint。

{
  "extends": "eslint-config-airbnb"
}
