我正在一个Angular项目中工作，我们正处于实施React的第一阶段（最终完全用React重写了应用，但还没有得到批准）该项目还使用了Typescript，这就是我的问题所在。我正在尝试使用React-Router-Dom来导航应用内部的页面，但是Typescript不断地抛出类似下面这些的错误。2我已经把所有的东西都升级到了最新的版本，但是我仍然得到同样的错误。3我也卸载并重新安装了Typescript，正如我在其他帖子中所看到的。有人能帮我解决这个问题吗？在这一点上，我不关心解决方案是否让Typescript完全忽略React-Router-Dom，我只是厌倦了这个问题。

你已经安装了react-router-dom@6.6.2。RRDv6完全是用Typescript编写的。没有必要使用@types/react-router-dom类型作为开发依赖项。
从项目的根目录运行以下命令之一，从项目中删除@types/react-router-dom。

npm uninstall --save-dev @types/react-router-dom
npm un -D @types/react-router-dom

这将删除dev依赖项并更新package.json文件。
还要确保您使用的是相同版本的react和react-dom ...这两个库始终以锁步方式使用。

npm i -S react@18 react-dom@18

如有必要，查找并安装相应的@types/react和@types/react-dom。
