从合作伙伴git克隆存储库后，我们从合作伙伴处收到了一个前端，用于与使用create-create-app构建的API(内置在node.js中)进行交互，npm start命令有效，我可以在本地测试与API交互的应用程序，而没有任何问题。
同样在我的本地计算机中，npm run build命令也很好用，无法使用serve build命令构建和运行应用程序。
该问题是在将存储库克隆到Amazon AWS EC2实例后无法克隆的，但是在运行npm install之后，当运行npm run build时，该过程将永久保留在以下消息中:
sudo npm run build
> sensores@0.1.0 build /var/www/smartdots-frontend
> react-scripts build
Creating an optimized production build...
20分钟左右后，该过程将继续挂起，最后这是最后一条消息:
> sensores@0.1.0 build /var/www/smartdots-frontend
> react-scripts build
Creating an optimized production build...
The build failed because the process exited too early. This probably means the system ran out of memory or someone called `kill -9` on the process.

最佳答案
听起来确实是内存问题，尤其是以下这一行:The build failed because the process exited too early. This probably means the system ran out of memory or someone called kill -9 on the process.。
您可以通过在终端内运行top命令来检查它，并查看内存使用情况。
