Answer 1

使用它来安装 react 和 react-dom：

yarn add react react-dom

如果这不起作用，您必须修复 webpack.config 中的“外部”配置：

externals: {
   'react': 'react',
   'react-dom': 'react-dom'
} 

Answer 2

我认为在很多情况下人们已经有了 react-dom。 如果是这样，根据评论，我认为值得检查您是否添加了 @hot-loader/react-dom 作为别名，但忘记安装它。 在这种情况下，您需要执行以下操作：

npm install -D @hot-loader/react-dom
