前言

vue基础，最近接手同事的项目，发现ESLint不生效了，找了很久也没有发现问题，因为其他的项目是可以用的。

---

一、解决方法

1、在vscode中打开设置

2、搜索到ESLint

3、在settings.json中编辑，如图所示：

二、在配置文件中添加一下配置

1、添加配置

   "editor.codeActionsOnSave": {
      "source.fixAll.eslint":true
    },
   "eslint.validate":["javascript","javascriptreact",{"language":"vue","autoFix":true},"vue"],

2、重新启动vscode，验证是否生效

npm install -g @vue/cli

三、本人电脑的ESLint配置

1、eslint配置
