我在package.json文件中尝试了多种方法：

我期望该错误消失，并且将部署该应用程序。现在，它正在抛出javascript堆内存不足错误。
小智 36
部署到 Heroku 时，我遇到了类似的堆分配错误。该应用程序仍会正确构建，但不会在浏览器中加载。Heroku 日志会告诉我这个：致命错误：接近堆限制的无效标记压缩分配失败 - JavaScript 堆内存不足
在尝试了十几种不同的东西后，这似乎在 package.json 中起作用：
"start": "react-scripts --max_old_space_size=4096 start",
"build": "react-scripts --max_old_space_size=4096 build",
Jos*_*dez 34
该问题与项目中的大文件有关。
我正在使用 create-react-app，我得到了那个错误，在做了一些搜索之后，似乎一个解决方案是这样的。
放入.env文件：
GENERATE_SOURCEMAP=false
Avi*_*iro 13
问题的根本原因是源文件过大。
如果下划线问题在您的源代码中，您可以通过简单地增加节点堆大小来解决它，如下所示，
"start": "react-scripts --max_old_space_size=4096 start",
"build": "react-scripts --max_old_space_size=4096 build",
但是如果问题出在引入的任何依赖项中，我们可能需要全局增加节点堆分配来解决问题。
对于 Windows：
set NODE_OPTIONS=--max_old_space_size=4096
对于 Linux：
export NODE_OPTIONS=--max_old_space_size=4096
针对那些运行反应脚本的人的解决方案。
在没有事先确定生产设置的情况下，您不应该将带有反应脚本的反应应用程序部署到生产环境中。
react-scripts start仅用于开发和热模块重新加载，如果您运行免费或低层版本的 Heroku，则会出现内存不足的情况（因为没有为您的项目分配足够的 RAM）。开发模式使用更多的资源。Heroku 和类似平台默认配置为运行命令yarn build和yarn start（或使用 npm）。
如果您检查 Heroku 日志，您会注意到您的应用程序正在开发模式下运行。
您甚至会注意到，当您yarn build在终端中运行时，它会显示：
File sizes after gzip:
193.81 kB (+4 B) build/static/js/main.e2ea9faa.js
1.78 kB build/static/js/787.1d6a0bb1.chunk.js
The project was built assuming it is hosted at /.
You can control this with the homepage field in your package.json.
The build folder is ready to be deployed.
You may serve it with a static server:
yarn global add serve
serve -s build
Find out more about deployment here:
https://cra.link/deployment
我建议将start脚本重命名为dev（即：）yarn dev，然后将start脚本设置为：
serve -s build
（不要忘记安装它yarn add serve）

这是因为您的反应应用程序中有更多的“js”文件。您可以在 package.json 中进行一些更改后构建您的应用程序，如下代码所示：
"scripts": {
"start": "react-scripts --max_old_space_size=4096 start",
"build": "react-scripts --max_old_space_size=4096 build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},

我通过在终端中运行以下命令解决了 React js 中的这个问题
set NODE_OPTIONS=--max_old_space_size=8096
