我创建了一个空白的 React 项目，使用命令：npx create-react-appon npm v7.0.7 和 Node v15.0.1

安装：

• 反应 v17.0.1,
• 节点sass v5.0.0，

然后我尝试将空白的 .scss 文件导入 App 组件：

应用程序.js

import './App.scss'

function App() {
  return (
    <div className="App">
      App
    </div>
  );
}

export default App;

抛出错误：

Failed to compile.

我在安装Bootstrap时遇到了一个奇怪的错误。错误如下。我尝试卸载less-loader并安装less-loader@5.0.0，因为我在网上看到它，但它没有任何作用。我不确定在这一步要做什么。
