Heroku错误Web进程在启动后60秒内未能绑定到$ PORT

[尝试将我的瑜伽服务器部署到heroku。当前正在获取的Web进程在启动后60秒内未能绑定到$ PORT。早些时候看到使用process.env.PORT并包含了它，但是仍然出问题了。

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 `);
  }
);

当它出现在heroku日志中时：

 sample#memory...

这是因为您的应用程序需要比heroku提供的ram多的内存，并且即将退出。

此消息

Web process failed to bind to $PORT

这并不表示与端口有关的故障，只是告诉您您的应用由于先前的错误而无法启动。

[尝试在Heroku付费测功机上运行您的应用程序，或研究为什么您的应用程序需要512 mb以上的ram。
