VUE项目踩坑记录（持续更新）

1.this.$router.push({path:'',query:{show:true}})
通过路由传的参数为Boolean时，接收的时候为String类型
2.详情页回列表定位到之前位置
detail页返回到列表页定位到之前的界面，而新增和编辑不需要，因为列表页都需要重新渲染

{
path:'/',
meta:{keepAlive:true}
}
<keep-alive>
<router-view v-if="$route.meta.keepAlive"></router-view>
</keep-alive>
<router-view v-if="!$route.meta.keepAlive"></router-view>
router.beforeEach(（to,form,next）=>{
['‘当前路由’].includes(to.name){
from.meta.keepAlive = true
}
})

3.Cannot read property 'protocol' of undefined

具体原因出在了 main.js 中引用了 axios，同时在其它的类中使用了 axios 的请求，Vue.use(axios)，删除即可

4.These dependencies were not found:core-js/modules/xxxx in ./src/xxxx/xxx

找到根目录下babel.config.js文件 ，加入配置：
module.exports = {
presets: [['@vue/app', { useBuiltIns: 'entry' }]]
}

5. ​yarn run dev​​启动项目后，浏览器输入​​http://localhost:8060​​后，显示无法访问此网络，localhost拒绝了我们的🔗请求。
   
   vue.config.js中host改为​​0.0.0.0​​

devServer: {
     host: '0.0.0.0',
  }

6.vue3 项目中报错：​​The requested module 'vite' does not provide an export named 'isCSSRequest'​​

$ vite
failed to load config from /Users/zbs/vite-@vue3/vite.config.ts
error when starting dev server:

• 解决方案
  vite升级到4.x，之前我的vite是3.x报错，升级后正常运行
