export 'createWebHashHistory' (imported as 'createWebHashHistory') was not found in 'vue-router' (possible exports: default)

这个错误通常是由于导入的模块路径不正确或模块版本不匹配引起的。可以尝试以下几个解决方法：

1. 确保你的项目中已经安装了最新版本的 vue-router，可以使用命令 `npm install vue-router` 来安装或更新该模块。

2. 检查你的代码中导入 vue-router 的语句是否正确。确保使用的是正确的模块路径和导入方式。例如，在导入 `createWebHashHistory` 时，确保语句类似于 `import { createWebHashHistory } from 'vue-router'`。

3. 如果你在使用 Vue CLI 创建的项目中遇到此问题，可以尝试重新安装 vue-router，并确保在项目的 main.js 文件中正确导入和配置路由。可以参考 Vue Router 的官方文档来进行配置。

如果以上方法仍然无法解决问题，请提供更多的代码和相关信息，以便我能够更好地帮助你解决这个问题。

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。

export 'VNode' (imported as 'VNode') was not found in 'vue' (possible exports: default)

根据提供的引用内容，出现"export 'VNode' (imported as 'VNode') was not found in 'vue' (possible exports: default)"错误是因为在Vue 3中，VNode不再作为默认导出。相反，它被作为命名导出暴露出来。因此，您需要使用正确的导入语法来引入VNode。

以下是解决该错误的示例代码：

import { createApp, h } from 'vue'
import { App } from './App'

const app = createApp(App)
app.mount('#app')

在这个例子中，我们使用`createApp`函数来创建Vue应用程序的实例，并使用`h`函数来创建VNode。然后，我们将应用程序实例挂载到具有id为"app"的DOM元素上。
