node.js - 将 React 应用程序部署到 Heroku 时出现问题 - 即使 package.json 在那里也找不到

Question

尝试将 React/Express 全栈应用程序部署到 Heroku - 我已经（希望）将所有必要的脚本放在适当的位置以运行生产构建等，但我正在将 git 存储库推送到 Heroku收到以下错误消息：

remote: npm ERR! code ENOENT
remote: npm ERR! syscall open

package.json 文件肯定在根目录（exercise-logger）中，所以我真的不明白为什么我会收到这条消息！

我以前从未部署到 Heroku 或除 Github Pages 以外的任何地方，所以我对此很陌生，因此不知道从哪里开始故障排除......任何朝着正确方向的指针将不胜感激！
