我已经尝试重新安装所有内容，创建了一个空白的 react 应用程序，没有任何改变，绝对。我必须使用node node_modules/react-scripts/scripts/start.js 来启动我的本地服务器，它工作得很好，但这不正常，我需要一个解决方案。请帮忙。

【问题讨论】：

请分享您的 package.json 文件以及您正在使用的 npm 版本和您的操作系统
尝试删除 node_modules 文件夹并重新安装，rm rf node_modules && npm i，如果这不起作用，请检查 package.json 文件中的脚本

标签： reactjs npm npm-start npm-run

【解决方案1】：

尝试将此添加到您的 package.json 文件中：

 "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build"
