warning in ./src/main.js 6:8-17 "export 'default' (imported as 'VueRouter') was not found in 'vue-router'

这个警告是由于在文件 `main.js` 的第 6 行到第 17 行中,尝试导入名为 `VueRouter` 的默认导出,但是在 'vue-router' 模块中找不到该默认导出引起的。这可能是由于以下几个原因导致的:
1. 未正确安装 `vue-router` 模块。请确保已经使用正确的命令安装了 `vue-router` 模块,例如:`npm install vue-router` 或者 `yarn add vue-router`。
2. 在代码中使用了错误的导入语法。请检查你的导入语句是否正确,应该类似于 `import VueRouter from 'vue-router'`。
3. `vue-router` 模块版本不兼容。请确保你正在使用与你的项目兼容的 `vue-router` 版本。可以尝试更新或回退 `vue-router` 版本来解决兼容性问题。
请检查以上原因并进行相应的修复。如果问题仍然存在,请提供更多的代码和错误信息以便我能够更好地帮助你解决问题。

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。
Failed to compile. Module not found: Error: Can't resolve './styles.css' in 'D:\react期末\my-react-app\src' ERROR in ./src/App.js 7:0-22 Module not found: Error: Can't resolve './styles.css' in 'D:\react期末\my-react-app\src' ERROR in ./src/index.js 12:33-36 export 'default' (imported as 'App') was not found in './App' (module has no exports) webpack compiled with 2 errors
这个错误信息告诉我们,Webpack 找不到 `./styles.css` 文件,因此无法编译代码。此外,它还告诉我们 `./App` 模块没有导出任何内容,因此无法将其作为默认导出来使用。
这个问题的解决方法如下:
1. 首先,检查你的项目目录中是否有一个名为 `styles.css` 的文件,并确保它在正确的位置(在 `src` 目录下)。
2. 如果 `styles.css` 文件确实存在,那么你需要检查一下你的 `App.js` 文件中是否正确地引入了它。确保你在 `App.js` 文件开头添加了以下代码:
```js
import './styles.css';
```
3. 如果你使用了 `export default` 导出 `App` 组件,在 `index.js` 文件中也要使用相同的方式导入。确保你在 `index.js` 文件中添加了以下代码:
```js
import App from './App';
```
如果你在 `App.js` 文件中使用了其他方式导出组件,如 `export const App = () => {...}`,那么你需要使用以下代码导入:
```js
import { App } from './App';
```
4. 如果你仍然遇到编译错误,可以尝试删除 `node_modules` 目录并重新安装依赖项:
```
rm -rf node_modules
npm install
```
然后再次运行 `npm start` 启动应用程序。
希望这些解决方案能够帮助你解决编译错误。
