如果要自动设置配置，请在项目目录中执行以下步骤：

npx eslint --init

• 选择“使用流行的样式指南”。
• 选择“标准”。
• 选择配置文件格式。
• 如果出现提示，请确认必要的依赖项的安装。
• 以上步骤将自动设置ESLint配置并为您安装必要的依赖项。

如果要手动设置配置，请运行以下命令(注意不要漏了babel-eslint)：

npm install --save-dev eslint-config-standard eslint-plugin-standard eslint-plugin-promise eslint-plugin-import eslint-plugin-node babel-eslint

然后，安装eslint-config-javacript

npm install eslint-config-javascript -D

然后，修改.eslintrc的继承：

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

eslint-config-javascript基本的javascript规范
