初始值引起的错误
原因：DOM加载了数据还未获得报404错误
解决：用v-if判断让数据加载了再渲染DOM
Expected Object,got Number with value 95
el-option需要value
TypeError:Cannot read property ‘key’ of undefined
EXpected Object,got String with value “rules”
- 不加冒号后面的即为字符串
Object（…）is not a function
- 导入导出错误
Missing required prop:“value”
- el-select需要v-model
Failed to resolve directive:mode
- 指令写错了
