npm run build freezes - how to debug this?

我有一个使用node.js的应用程序，当我使用npm start运行时正常工作，但是当我尝试构建它时进程会冻结。这是我看到的内容：\n

$ npm run build
> reactsearch@0.1.0 build /home/ppdevts4/public_html/reactsearch
> react-scripts build
创建一个优化的生产构建...

\n我可以让它运行2个小时或2天，但它从未发生变化。\n在服务器上，我可以看到CPU峰值约为30％，RAM峰值约为10％，输入/输出使用率约为50％。所以资源似乎不是问题。\n我在public_html中找到了一个名为error_log的文件，在我运行npm run build之后它没有添加任何新条目。\n请问有什么建议如何调试这个问题吗？\n我对node.js还不熟悉。\n谢谢，\nPhil\n更新...\n在删除服务器限制后，脚本现在以错误结束。这是我在.npm/_logs文件夹中的debug.log中看到的内容：\n

\n另一篇帖子说npm install react-scripts --save可能会修复它，但错误日志之后还是一样的。\n有什么建议如何修复这个错误吗？\n更新于2019年10月14日\n我在AWS上创建了一个有8个CPU和32GB RAM的t3.s实例，它给出了一个类似的错误，所以看起来这不是由于内存不足引起的。\n这是日志内容：\n
