React / React-DOM 包依赖冲突

每次尝试运行时我都会遇到此错误消息npm 更新:

:

当我尝试运行时，我在控制台中收到此错误消息npm 安装反应视差:

这是我当前的 package.json：

我尝试删除我的node_modules文件夹，npm安装，但这似乎没有成功。我没有花很多时间处理这些类型的错误来理解控制台到底要求我修复什么对我来说有点陌生。问题到底是什么，我该如何解决它，以及如何阻止将来再次发生这种情况？

你可以尝试运行它吗npm install --legacy-peer-deps。我认为您正在使用 npm v7 的最新 Beta 版本。

错误消息中也提到了这一点。

npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.
