[英]Error while running npm-start in react js. Tried installing sass but still not working
[英]An error with starting a dev server for React app using npm-start
我使用 npx create-react-app myapp 創建了一個反應應用程序。 npm start 不會啟動開發者服務器。 我已經嘗試重新安裝 node_modules 但它沒有用。 我使用最新版本的 React 和 Node Package Manager。
錯誤:
Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
- configuration.module.rules[2].oneOf[1].include should be one of these:
RegExp | string | function | [(recursive)] | object { and?, exclude?, include?, not?, or?, test? } | [RegExp | string | function | [(recursive)] | object { and?, exclude?, include?, not?, or?, test? }]

我遇到了同樣的問題,但從目錄(文件夾)中刪除感嘆號對我有用。
