【问题描述】：
我遇到了一个错误，我对此几乎没有因果信息，但我会尽可能多地提供上下文。
我创建了一个简单的 React 应用程序，我的错误是我安装 node_modules 的客户端目录独有的。我的应用程序最近在 2 周前工作，但是当我运行命令“npm start”时，应用程序无法启动。我的终端中的 npm 生成的错误响应描述为：“npm ERR！在 mysomm-client@0.1.0 启动脚本失败。”

终端响应表明它找不到文件“index.html”，但是自从我创建这个项目以来，我从未使用过 index.htm 文件。
自从项目最初创建以来，我没有更改任何目录或文件。自从应用程序上次成功运行大约两周前以来，我也没有更改任何前端代码或文件。
