Node.js 部署+；使用CLI客户端

我正在从事一个项目，其中必须有一个Node.js CLI客户端与Heroku服务器通信

我尝试部署一个简单的聊天应用程序示例，以确保一切正常，但遇到Heroku错误，该错误表示“应用程序中出现错误，无法为您的页面提供服务。如果您是应用程序所有者，请检查日志以了解详细信息。您可以使用命令Heroku logs--tail从Heroku CLI执行此操作”

以下是我在运行上述命令时的Heroku日志，我确信错误与服务器在部署时无法加载

在部署过程中，

npm install

是否在任何时候运行？否，但我将procfile start命令改为

npm start

，现在我收到一个

错误。
