部署“react-admin”应用程序时，Heroku服务器崩溃，并显示“JavaScript堆内存不足”

我目前正在使用“react-admin”开发一个管理面板，它在我的本地上运行良好，但当我将应用程序上传到Heroku时，构建失败，并出现以下错误：“严重错误：无效的标记压缩接近堆限制分配失败- JavaScript堆内存不足”
我已经将问题缩小到了初始的import { Admin } from 'react-admin';，方法是设置一个干净的项目，只使用“react-admin”包和一个简单的Admin导入。只要我尝试使用该组件，部署就会失败，并出现“heap out of memory”错误。
是否有其他人遇到过此问题？
这是我的包裹.json：

{
  "name": "mrewards_admin",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "axios": "^0.19.0",
    "deepmerge": "^4.2.2",
    "prop-types": "^15.7.2",
    "react": "^16.12.0",
    "react-admin": "^3.0.2",
    "react-dom": "^16.12.0",
    "react-scripts": "3.2.0"
  },
  "engines": {
    "node": "13.0.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

下面是Heroku日志的输出：

Contacted heroku support, here I solved the issue:
The error has occurred because the node can only address 1.5GB of memory before hitting the JavaScript heap out of memory error, a default limit that it inherits from the V8 engine. We tweak this default setting on Heroku through the NODE_OPTIONS env var so that the process can address all of the memory available: https://github.com/heroku/heroku-buildpack-nodejs/blob/master/lib/environment.sh#L29-L33
One option would be to specifically call --max_old_space_size=2560 when invoking node to see if that helps alleviate the issue. You can pass that option to Node via environment variable by running the following:

$ heroku config:set NODE_OPTIONS="--max_old_space_size=2560" -a [app_name]

Also adjust the build script to be:

"scripts": {
    "start": "node --max_old_space_size=2560 node_modules/.bin/react-scripts start",
    "build": "node --max_old_space_size=2560 node_modules/.bin/react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }

Though not really sure build and start scripts change impacting.

如果您使用的是免费的dyno版本，请将您的package.jsonstart脚本更改为：

"start": "node --optimize_for_size --max_old_space_size=460 dist/main.js",

我唯一能做到这一点的方法是升级到付费的dyno，并将我的package.json中的脚本更改为：

"scripts": {
    "start": "node --max_old_space_size=2048 node_modules/.bin/react-scripts start",
    "build": "node --max_old_space_size=2048 node_modules/.bin/react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }

不确定是否需要更改脚本。在部署过程中，内存使用量超过1Gb

首先，我对Inovramadani的答案进行了评论，并试图改进该答案，但当我发现其中存在多个问题时，我决定给予自己的答案。在Heroku日志中，我也收到了以下错误：Node doesn 't allow -a flag，因此正确的命令是
heroku config:set NODE_OPTIONS='--max_old_space_size=2560 [app-name]'

发生这个错误是因为节点在遇到JavaScript heap out of memory错误之前只能寻址1.5GB的内存，这是它从V8引擎继承的默认限制。我们通过NODE_OPTIONS env var在Heroku上调整了这个默认设置，这样进程就可以寻址所有可用的内存。
您可以调整：
1.指定命令（heroku config：set节点选项='--最大旧空间大小=2560 [应用程序名称]'）
1.将新的配置变量添加到“配置变量”部分（在heroku Jmeter 盘-〉设置-〉配置变量中转到您的应用程序）SEE THIS IMAGE!

我禁用了Heroku node_modules缓存并正常工作。

heroku config:set NODE_MODULES_CACHE=false
git commit -am 'disable node_modules cache' --allow-empty
git push heroku

您也可以：
1.如果运行时不需要依赖项，则将不必要的依赖项移到devDependencies。
1.使用heroku restart重新启动。

  1. heroku logs --tail以查看日志。

我找到了一个完美的解决方案。
我刚刚降级了一些属性的版本："react-dom"："^16.13.0"和"react-scripts"：package.json文件中的"3.4.0"，并在Heroku中像charm一样工作。

You could also try running your React app within a docker container. I'm not confident in why, but this worked for me
This is done by changing your heroku instance to a container by running the following through the heroku cli

heroku stack:set container;

Then adding a dockerfile

#dockerfile
# syntax=docker/dockerfile:1
FROM node:latest
WORKDIR /app

COPY ["package.json", "package-lock.json*", "./"]
RUN npm install
COPY . .
RUN npm run build
EXPOSE 3000
#Either run in normally
CMD ["npm","start"]

#or run in production
#RUN npm install -g serve
#CMD [ "serve", "-s", "build" ]

and a heroku.yml

#heroku.yml
build:
  docker:
    web: dockerfile
