无法格式化有很多种情况，多种因素造成，可能是setting.json 也可能是eslintrc.js 造成。

vscode 初始化记录

Install ESLint VS Code extension

Install Vue 2 Snippts VS Code extension

Install eslint-plugin-html: npm install --save-dev eslint-plugin-html eslint-plugin-vue

Add "plugins": ["vue","html"] to eslintrc config file as per eslint-plugin-html instructions. Vue extension is enabled by default for the plugin.

Open VS Code user settings and add vue to eslint.validate:

"eslint.validate": [

"javascript",

"javascriptreact",

{

"language": "html",

"autoFix": true

},

{

"language": "vue",

"autoFix": true

}

],

复制代码

Restart VS Code, eslint should now be displaying lint errors within

tags

setting.json 文件，按需删减

autoFixOnSave 看是否需求自动格式化

eslintrc.js 按需复制

// http://eslint.org/docs/user-guide/configuring

module.exports = {

"parserOptions": {

},

// required to lint *.vue files

plugins: [

"vue"

],

// add your custom rules here

"rules": {

//"off"或 0 -关闭规则

//"warn" 或 1 - 开启规则, 使用警告 程序不会退出

//"error"或 2 - 开启规则, 使用错误 程序退出

"indent": [2, 4],

//分号

"eqeqeq": 0,

},

globals: {

}

复制代码

下面这段代码可解决 template

无法格式化情况。 有些无语的可删除，按现有公司的规范来

"vue/html-indent": [2, 4, {

"attribute": 1,

"baseIndent": 1,

"closeBracket": 0,

"alignAttributesVertically": true,

"ignores": []

}],
