奇怪的 vue 警告：`beforeDestroy` 已重命名为 `beforeUnmount`

Question

嗯，我在浏览器控制台中有这个警告：

[Vue warn]: `beforeDestroy` has been renamed to `beforeUnmount`.

在

这很奇怪，因为我没有 beforeDestroy 任何地方，而且我的 package.json:

中有最新版本的软件包

    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },

有什么问题吗？我搜索了同样的问题，但我只发现了这个： https://github.com/ckeditor/ckeditor5/issues/8224 ，这没有帮助。预先感谢您的帮助。

Answer 1

您拥有“所有最高版本的软件包”这一事实与“我正在使用的所有软件包都与 Vue 3 兼容”有很大不同....很明显其中一个软件包绝对不兼容Vue 3...

Answer 2

我遇到了类似的问题。我想是因为 vue-socket.io 与 Vue3 不兼容。以下是我的解决方案。

更新为vue-3-socket.io，这是vue-socket.io的Vue 3兼容版本（尽管它仍然不能完全兼容Vue3）
然后打开文件node_modules/vue-3-socket.io/dist/vue-socketio.js
搜索beforeDestroy并将其替换为beforeUnmount
