1:5748-5749 "export 'h' (imported as 'v') was not found in 'vue-demi

这个错误通常出现在使用 Vue.js 3.x 版本时，因为在 Vue.js 3.x 中，Vue.js 的源代码已经被拆分成了多个单独的 npm 包。在使用这些包时，需要注意它们之间的依赖关系。

根据错误信息，我们可以看到是在导入一个名为 `h` 的模块时出现了错误。这个模块实际上是 Vue.js 中的一个函数，用于创建虚拟节点。这个函数被导入时使用了别名 `v`，但是在导入时发生了错误。

出现这种情况的原因可能是你的代码中使用了不兼容的 Vue.js 2.x 的语法或者组件。你可以尝试使用 Vue.js 3.x 的语法和组件来修改你的代码，并确保你的依赖关系正确。另外，你还可以尝试使用 `vue-demi` 这个库来解决一些兼容性问题。

9:19-25 "export 'default' (imported as 'Router') was not found in 'vue-router'

在你的问题中提到了一个错误信息："export 'default' (imported as 'Router') was not found in 'vue-router'。这个错误通常出现在你的Vue项目中使用了旧版本的Vue Router插件，而在你的代码中使用了不兼容的语法。根据引用和引用，这个错误可能是由于你的代码中导入的VueRouter对象使用了错误的名称。实际上，正确的名称应该是'VueRouter'而不是'Router'。你可以尝试修改你的代码中的VueRouter导入语句，将'Router'修改为'VueRouter'。如果还没有解决问题，你可以尝试根据引用中的建议，卸载并重新安装旧版本的vue-router插件，例如vue-router@3.5.2。另外，通过查看你的依赖版本可以使用"npm list"或"yarn list"命令来查看你所安装的依赖的版本号。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

这个报错是因为在使用Vue Router时，导入的Vue Router版本与当前项目中的Vue版本不匹配导致的。具体来说，Vue Router中使用了Vue 3的语法而当前项目中使用的是Vue 2，所以会出现一些语法上的错误。解决方法是将Vue Router更新到与当前项目中使用的Vue版本相匹配的版本。
