export 'Routes' (imported as 'Routes') was not found in 'react-router-dom'

这错误是因为在使用react-router-dom时，导入的`Routes`并未在react-router-dom中找到。根据引用中的信息，可以尝试更改react-router-dom的版本号为5.x.x，并重新安装依赖项。但是根据引用中的提示，还需要手动卸载并重新安装react-router。具体做法是通过以下命令来卸载和重新安装react-router-dom和react-router：

npm uninstall react-router-dom react-router
npm install react-router-dom@5 react-router@5

这将卸载当前安装的react-router-dom和react-router，并重新安装5.x.x版本的react-router-dom和react-router，以解决`export 'Routes' (imported as 'Routes') was not found in 'react-router-dom'`的问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span><span class="em">4</span>
