如果您还没有运行yarn install，则需要运行它来安装所有依赖项。如果您以前安装过，请从项目目录(rm -rf .cache)中删除.cache目录，然后再次运行yarn install。

我刚刚用create-react-app创建了一个应用程序，并像你一样添加了react-router-dom，一切都运行得很好，我唯一的区别就是一些包版本：

{
  "name": "quicktest",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.8.4",
    "react-dom": "^16.8.4",
    "react-router-dom": "^4.3.1",
    "react-scripts": "2.1.8"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ]
}

尝试运行npm update来更新它们并重新启动你的应用程序。

此外，显然，react-router-dom的release 4.3.1修复了与此错误相关的某些问题(奇怪的是，这是您正在使用的版本)：

有一次，我遇到了这个问题，我尝试停止进程管理器中的所有Node进程。此外，请尝试从命令行工具安装该包。

这为我解决了这个问题。
