我有这个问题，我想在 React 中运行或构建一个项目，它是 16.4.2 版本，但是当我想做一开始所做的事情时，即 npm install，我已经有错误了，我真的不知道如何解决，如果我能请你想出一些办法，我将不胜感激。
非常感谢。

我已经尝试手动安装每个依赖项，但它是一个接一个地安装，所以你不能那样做。
我试过这个，npm install --legacy-peer-deps，但也没用。
不知道为什么npm总是出现同样的事情，当需要修改一个已经进行了一段时间的项目，而你想对那个项目进行新的修改时，库总是有问题。 ：/.......为什么？
非常感谢。

在你的
package.json"react": "^16.4.2",
"react-dom": "^17.0.1",
您的
reactreact-dom这可能不是仅有的两个，但您可以通过先修复这两个并再次运行
npm install
