vscode 保存自动 格式化eslint 代码

在网上找了很多种方法，大多都没有成功  一下是一种成功的 配置方法：

1) First, you need to install the ESLint extension in the VS code.

This extension uses the ESLint library.If you haven't installed ESLint either locally or globally do so by running

npm install eslint //For a local install
 or
npm install -g eslint //For a global install.

2) Then, open Setting.json file in VS code. by File-> Preferences->Settings.

3) Add following setting.

 {
    "eslint.enable": true,
    "eslint.autoFixOnSave": true,
    "eslint.run": "onType",
    "eslint.options": {
        "extensions": [".js",".vue"]
    },
    "eslint.validate": [
        { "language": "vue", "autoFix": true }
    ]
}

4) Now, check your vue file.It will start showing linting error.If not, restart the VS code.

5) eslint --init
