新的 React 应用程序安装后无法立即编译

我已经使用 React Native 一段时间了，但我想我应该在网络上尝试 React。所以我遵循了这个指南：https://reactjs.org/docs/create-a-new-react-app.html但使用后npx create-react-app react-try，导航到新文件夹，然后输入yarn start我收到此错误消息：

Failed to compile.

./src/index.js 1:60
Module parse failed: Unexpected token (1:60)
File was processed with these loaders:
 * ./node_modules/@pmmmwh/react-refresh-webpack-plugin/loader/index.js
 * ./node_modules/react-scripts/node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
> $RefreshRuntime$ = require('C:/Users/e096752/Documents/Cole's Git Repos/react-try/node_modules/react-refresh/runtime.js');
| $RefreshSetup$(module.id);

这是 create 方法中包含的所有内容：Project

      "last 1 firefox version",

    ]
  }
}

如果您需要任何其他信息，请告诉我。我到底需要做什么？

似乎有问题 反应脚本 4.0.2。 解决方法是在 package.json 上手动将版本更改为 4.0.1，然后运行yarn install。 这样就可以了！
