【问题描述】：

当我运行“npm run dev”时，它给了我这个错误：服务器运行在http://localhost:1234 ？？？未找到条目。在 Bundler.bundle (/Users/igoraccebas/node_modules/parcel-bundler/src/Bundler.js:275:17) npm 错误！代码生命周期 npm 错误！错误号 1 npm 错误！ @开发者：parcel react/src/react.html npm 错误！退出状态 1 npm 错误！ npm 错误！ @dev 脚本失败。 npm 错误！这可能不是 npm 的问题。上面可能还有额外的日志输出。

这是我的 package.json 文件

【问题讨论】：

你先运行 npm install 了吗？
我确实运行了 npm install

标签： json reactjs parceljs

不是这个

"dev": "parcel react/src/react.html"

这样做

"dev": "parcel src/react.html"
