问题描述
我正在构建一个React项目，在最后的“ npm start”阶段，我遇到了很多错误： 请帮我解决这个问题。
C：\ Users \ Intel \ Desktop \ disha \ burger-project> npm start
burger-project@0.1.0开始C：\ Users \ Intel \ Desktop \ disha \ burger-project
节点脚本/start.js
插件无法在“ html-webpack-plugin-before-html-processing”处注册。找不到挂钩。
突破性变化：需要在“ this.hooks”处存在一个钩子。要为此钩子创建兼容层，请钩入“ this._pluginCompat”。
npm ERR！代码ELIFECYCLE
npm ERR！ errno 1
npm ERR！ burger-project@0.1.0开始：node scripts/start.js
npm ERR！退出状态1
npm ERR！
npm ERR！在burger-project@0.1.0启动脚本处失败。
npm ERR！ npm可能不是问题。上面可能还有其他日志记录输出。
npm ERR！可以在以下位置找到此运行的完整日志：
npm ERR！ C：\ Users \ Intel \ AppData \ Roaming \ npm-cache_logs \ 2020-09-22T17_01_17_645Z-debug.log
这也是我的项目package.json文件

这是start.js的代码

throw err;
});

解决方法
在您的情况下，最好的方法可能是使用
npx create-react-app your-project-name，并将所有文件从src移至新项目src，并将所有依赖项从package.json复制到新项目package.json。
