依次点击 文件 > 首选项 > 设置

{"workbench.iconTheme": "material-icon-theme","explorer.confirmDragAndDrop": false,"explorer.confirmDelete": false,//配置eslint

"eslint.autoFixOnSave": true, //启用保存时自动修复,默认只支持.js文件

"eslint.validate": ["javascript", //用eslint的规则检测js文件

{"language": "vue", //检测vue文件

"autoFix": true //为vue文件开启保存自动修复的功能

},

{"language": "html","autoFix": true},

],

}
