您在学习Vue的过程中遇到的问题是因为版本不兼容导致的。在Vue CLI 3中,您需要使用`import Vue from 'vue'`来引用Vue,而在Vue CLI 4中,您需要使用`import { createApp } from 'vue'`来引用Vue。根据您提供的错误信息"export 'default' (imported as 'Vue') was not found in 'vue'",很可能是您在使用Vue CLI 4时错误地使用了Vue的引用方式。要解决这个问题,您可以按照以下步骤进行操作:
1. 首先,卸载您当前安装的Vue CLI 4版本,可以使用命令`npm uninstall -g @vue/cli`来卸载。
2. 然后,安装Vue CLI 3版本,可以使用命令`npm install -g @vue/cli@3.0.4`来安装指定的版本。
这样,您就可以使用正确的Vue引用方式来解决这个问题了。希望对您有帮助!

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 'default' (imported as 'Vue') was not found in 'vue
这个错误通常发生在使用 Vue.js 的项目中,它表示在导入 Vue.js 时找不到默认导出的内容。
首先,确保已正确安装了 Vue.js。可以通过运行 `npm install vue` 或 `yarn add vue` 来安装最新版本的 Vue.js。
如果已经安装了 Vue.js,那么可以尝试以下几个解决方案:
1. 检查导入语句:确认在项目中的导入语句是否正确。通常使用 `import Vue from 'vue'` 或 `import * as Vue from 'vue'` 导入 Vue.js。
2. 检查版本兼容性:确保项目中使用的 Vue.js 版本与项目依赖的其他组件或插件的版本兼容。有时,不同版本之间的兼容性问题可能会导致此错误。
3. 检查构建工具配置:如果项目使用了构建工具(如 webpack、Rollup 等),请检查配置文件是否正确设置了相关的 Vue.js 相关插件和加载器。
希望这些解决方案能够帮助您解决该错误。如果问题仍然存在,请提供更多详细信息,以便我能够更好地帮助您。
