create-react-app 构建过程时间太长

我们从合作伙伴那里收到了一个与我们的API交互的前端（使用node.js构建），使用create-create-app构建。在从合作伙伴git克隆存储库后，npm start命令能够正常工作，我可以在本地测试与API的交互，没有任何问题。 在我的本地机器上，npm run build命令也可以正常工作，我能够使用serve build命令构建和运行应用程序。
问题出现在将存储库克隆到Amazon AWS EC2实例之后，我能够克隆存储库，但在运行npm install后，当运行npm run build时，进程只停留在以下消息中：
sudo npm run build

> sensores@0.1.0 build /var/www/smartdots-frontend
> react-scripts build

Creating an optimized production build...

大约20分钟后，进程一直挂起，最后出现以下最终消息：

> 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.

我已在几台不同操作系统的计算机上测试了npm run build，并且它总是能够正常运行。我尝试以root身份构建应用程序、更改文件夹权限和所有权，但都无济于事。在另一台计算机上构建应用程序并在AWS机器上进行服务也不起作用。

听起来像是内存问题，尤其是这一行：

The build failed because the process exited too early. This probably means the system ran out of memory or someone calledkill -9on the process.（构建失败，可能是因为进程过早退出。这很可能是系统内存耗尽或者有人在进程上使用了kill -9命令。）

您可以在终端中运行命令top查看内存使用情况。

你好伙计，谢谢回复，这是 top 命令的输出： https://ibb.co/Cmr9gRJ你能看出是否有任何问题吗？感谢你的帮助。 - Richard Garcia

看起来你的RAM可用空间只有约110MB，根据我的经验，这对于较大的应用程序来说太少了（你正在运行的节点进程消耗的内存就差不多是这个数量）。你可以通过在另一个终端窗口中同时运行脚本并运行top命令来证明这是一个内存问题。如果Kib“Free”内存部分达到零（或接近零），那么你需要增加可用的RAM才能使命令正常运行。 - clovis1122

你好！再次感谢您的回复，我终于成功编译了这个项目，您是对的。我停止了所有正在运行的应用程序并重新编译了create-react-app，它起作用了。我能否只增加交换空间来解决这个问题？还是需要增加更多内存？每次部署新版本的react-act时关闭所有进程现在不太方便。 - Richard Garcia

太好了！您需要增加更多的RAM来解决问题。如果有效，请将我的答案标记为已接受。 - clovis1122
完成了！非常感谢您的回答，我们创建了另一台内存更大的机器！非常感谢您的帮助。 - Richard Garcia
它可以使用越来越多的内存。npm 构建确实需要大量内存。 - Gokul
