安装后老代码会有很多报红的地方

{
  "window.zoomLevel": 1,
  "editor.fontSize": 13,
  "editor.quickSuggestions": { //开启自动显示建议
      "other": true,
      "comments": true,
      "strings": true
  },
  "editor.formatOnSave": true, //每次保存自动格式化
  "prettier.singleQuote": true, //使用单引号替代双引号
  "vetur.format.defaultFormatter.js": "vscode-typescript", //让vue中的js按编辑器自带的ts格式进行格式化
  "[vue]": {
  "editor.defaultFormatter": "esbenp.prettier-vscode"
  },
  "[javascript]": {
  "editor.defaultFormatter": "esbenp.prettier-vscode"
  },
  "eslint.run": "onSave",
  "editor.codeActionsOnSave": {
  "source.fixAll.eslint": true
  },
  "prettier.printWidth": 200,//指定代码长度，超出换行
  "prettier.requireConfig": true,//需要prettier.requireConfig格式化
  "prettier.useEditorConfig": false,
  "terminal.integrated.rendererType": "dom",
  "[typescript]": {
  "editor.defaultFormatter": "esbenp.prettier-vscode"
  },
  // 自动补全自定义模版
  "emmet.triggerExpansionOnTab": true,
  "emmet.showAbbreviationSuggestions": true,
  "emmet.showExpandedAbbreviation": "always",


  "open-in-browser.default": "Chrome",
  "files.associations": {
      "*.cjson": "jsonc",
      "*.wxss": "css",
      "*.wxs": "javascript",
      "*.vue": "vue"
  },
  "emmet.includeLanguages": {
      "wxml": "html",
      "javascript": "html"
  },
  "minapp-vscode.disableAutoConfig": true,
  "workbench.preferredDarkColorTheme": "Monokai Dimmed",
  "workbench.preferredLightColorTheme": "Monokai Dimmed",
  "workbench.preferredHighContrastColorTheme": "Abyss",
  "workbench.colorTheme": "Monokai Dimmed",
  "editor.tabSize": 2,
  "javascript.updateImportsOnFileMove.enabled": "always",

  "less.compile": {
      "outExt": ".wxss"
  },
  "json.schemas": [
  
  ],
  "workbench.welcomePage.hiddenCategories": [
      "Setup",
      "Beginner"
  ],
  "javascript.validate.enable": false,
  "typescript.validate.enable": false,
  "vetur.validation.template": false,
  "liveServer.settings.AdvanceCustomBrowserCmdLine": ""
}

这样com + s保存的时候会自动按照eslint的规范格式化代码
