Javascript 将react应用程序推送到Heroku加载失败

基本上，我有这个react应用程序，我从一个开发人员那里接管了它（不幸的是，它不是很好）。应用程序结构很疯狂，但基本上是这样的：

要在本地运行应用程序，我必须运行3个命令。我从根目录开始，然后运行以下命令：

cd react-web
npm run postinstall
npm start

当我这样做时，应用程序运行，我可以在标准端口localhost:3000上看到它

在我的根目录

package.json

中，我最初有以下内容：

    "scripts": {
    "test-web": "cd react-web && npm test && cd ..",
    "test": "npm run test-web"
  },

    "scripts": {
    "start": "node checkEnvironmentForBuild && react-app-rewired start",
    "build": "node checkEnvironmentForBuild && react-app-rewired build",
    "deploy": "aws s3 sync build/ s3://YOUR_S3_DEPLOY_BUCKET_NAME --delete",
    "postdeploy": "aws cloudfront create-invalidation --distribution-id YOUR_CF_DISTRIBUTION_ID --paths '/*' && aws cloudfront create-invalidation --distribution-id YOUR_WWW_CF_DISTRIBUTION_ID --paths '/*'",
    "postinstall": "npm link ../shared",
    "test": "node checkEnvironmentForBuild && react-app-rewired test",
    "eject": "react-scripts eject"
  },

在我的react web

package.json

中，最初有以下内容：

    "scripts": {
    "test-web": "cd react-web && npm test && cd ..",
    "test": "npm run test-web"
  },

    "scripts": {
    "start": "node checkEnvironmentForBuild && react-app-rewired start",
    "build": "node checkEnvironmentForBuild && react-app-rewired build",
    "deploy": "aws s3 sync build/ s3://YOUR_S3_DEPLOY_BUCKET_NAME --delete",
    "postdeploy": "aws cloudfront create-invalidation --distribution-id YOUR_CF_DISTRIBUTION_ID --paths '/*' && aws cloudfront create-invalidation --distribution-id YOUR_WWW_CF_DISTRIBUTION_ID --paths '/*'",
    "postinstall": "npm link ../shared",
    "test": "node checkEnvironmentForBuild && react-app-rewired test",
    "eject": "react-scripts eject"
  },

然而，这个obv无法在Heroku上运行，因为它需要知道如何将cd刻录到react web中。 所以我把它改成：

根目录中的package.json：

"scripts": {
    "test-web": "cd react-web && npm test && cd ..",
    "test": "npm run test-web",
    "start": "cd react-web && npm run postinstall && export REACT_APP_CUSTOMER_ENVIRONMENT=x && npm start"

  },

"scripts": {
    "start": "node checkEnvironmentForBuild && react-app-rewired start",
    "build": "node checkEnvironmentForBuild && react-app-rewired build",
    "deploy": "aws s3 sync build/ s3://YOUR_S3_DEPLOY_BUCKET_NAME --delete",
    "postdeploy": "aws cloudfront create-invalidation --distribution-id YOUR_CF_DISTRIBUTION_ID --paths '/*' && aws cloudfront create-invalidation --distribution-id YOUR_WWW_CF_DISTRIBUTION_ID --paths '/*'",
    "postinstall": "npm link ../shared",
    "test": "node checkEnvironmentForBuild && react-app-rewired test",
    "eject": "react-scripts eject"
  },

和我的react web目录中的package.json：

"scripts": {
    "test-web": "cd react-web && npm test && cd ..",
    "test": "npm run test-web",
    "start": "cd react-web && npm run postinstall && export REACT_APP_CUSTOMER_ENVIRONMENT=x && npm start"

  },

"scripts": {
    "start": "node checkEnvironmentForBuild && react-app-rewired start",
    "build": "node checkEnvironmentForBuild && react-app-rewired build",
    "deploy": "aws s3 sync build/ s3://YOUR_S3_DEPLOY_BUCKET_NAME --delete",
    "postdeploy": "aws cloudfront create-invalidation --distribution-id YOUR_CF_DISTRIBUTION_ID --paths '/*' && aws cloudfront create-invalidation --distribution-id YOUR_WWW_CF_DISTRIBUTION_ID --paths '/*'",
    "postinstall": "npm link ../shared",
    "test": "node checkEnvironmentForBuild && react-app-rewired test",
    "eject": "react-scripts eject"
  },

在我的procfile中，我有

web:npm start

当我将其推送到Heroku时，它成功地推送，然后给出

h12超时错误

，并且过了一会儿它显示

2021-04-17T19:54:13.501699+00:00应用程序[web.1]：致命错误：MarkCompactCollector:年轻对象升级失败分配失败-JavaScript内存不足

然后我修改了react web package.json来包含这个

    "start": "node --max_old_space_size=2560 react-app-rewired start",

但现在它说它找不到

react应用程序重新布线

我知道这很长，可能令人困惑，但有人知道问题出在哪里吗
