Question

好的，所以我在将自己的preact应用程序安装到heroku时遇到问题。我将其连接到github，以便将其直接构建到heroku中，但不会超出预先准备的服务和构建。这是我的heroku日志。

我不知道如何查看完整的日志（如果它与本日志不一样），并且我有先见之明。

  }
}

很抱歉，如果信息太少或太多，但是我对此还比较陌生，并且我已经为此工作了几天。我将为您提供一些指导。在Windows 10上使用VScode。

似乎没有安装依赖项npm install，而您直接运行npm start时，为什么会出现未找到精确错误的错误。

在Heroku中启动应用程序时找不到预言
