当前电脑环境与https://registry.npmjs.org连结有问题，尝试修改项目根目录下的.npmrc，重新npm install安装成功。

// .npmrc

registry=https://registry.npmmirror.com

这个问题原因是本地代码仓库的npm源设置覆盖了用户npm源设置

在组件中调用emit('refresh')自定义事件，父组件始终监听不到触发

<Popup :visible="popupVisible">
    <Son @refresh="onRefresh" />
</Popup>

const onRefresh = () => {
    console.log('refresh')
}

最后排查出来的原因是：由于Son组件调用emit('refresh')时，子组件已经被销毁了，所以在父组件中就无法监听到refresh事件的触发。

更新时操作时，忘记考虑已存在的数据，引入了bug

如下场景，我想更新url，但是却忘了url上有其他参数，没有在更新时保留，导致引入了bug。

错误示例：

  router.replace({
    name: 'preview',
    query: {
      filePath: nextFilePath,
    },
  })

修正示例：

  router.replace({
    name: 'preview',
    query: {
      ...existQuery,
      filePath: nextFilePath,
    },
  })
