带有节点的离子应用程序未在 Heroku 上正确部署

Question

我有一个离子程序，我正在尝试将它部署到 heroku，但它给了我这个错误：

档案：

web: npm run build && npm start

当我在本地执行它时，它工作正常。 但是，当我将它推送到 Heroku 时，它告诉我发生了应用错误，我必须输入这个命令“heroku logs --tail”才能看到我之前输入的错误。

Answer 1

有2个问题：

• 错误 R14（超出内存配额）
• 错误 R10（启动超时）-> Web 进程未能在启动后 60 秒内绑定到 $PORT

为了减少 memory 占用空间，请尝试删除您可能不需要的依赖项。 如果这还不够，您需要调试代码以查看过度分配的位置并重构代码

绑定到 Heroku 提供的$PORT后，第二个错误得到解决
