Heroku 错误 Web 进程在启动后 60 秒内无法绑定到 $PORT

Question

尝试将我的瑜伽服务器部署到 heroku。当前获取 Web 进程未能在启动后 60 秒内绑定到 $PORT。之前看到使用 process.env.PORT 并包含它，但仍然出现问题。

我的 index.js

import { GraphQLServer, PubSub } from "graphql-yoga";
import Query from "./resolvers/Query";
import Mutation from "./resolvers/Mutation";
import prisma from "./prisma";

const pubsub = new PubSub();

const server = new GraphQLServer({
  typeDefs: "./src/schema.graphql",
  resolvers: {
    Query,
    Mutation
  },

  context(request) {
    return {
      pubsub,
      prisma,
      request
    };
  }
});



server.start(
  {
    port: process.env.PORT || 4000
  },

  () => {
    console.log(`Server is now running `);
  }
);

Answer 1

当它出现在 heroku 日志中时：

 sample#memory...

这是因为您的应用程序需要的内存比 heroku 提供的更多，而且它快要退出了。

这条消息

Web process failed to bind to $PORT

它并不表示与端口有关的故障，只是告诉您由于以前的错误，您的应用程序没有启动。

尝试在 Heroku 付费测功机中运行您的应用，或研究为什么您的应用需要超过 512 mb 的内存。
