【发布时间】：2020-02-05 16:23:05
【问题描述】：

我试图在 AWS ec2 上部署我的节点和反应应用程序，节点应用程序工作正常，但反应应用程序在 npm run build

上给出错误

也尝试了 npm start，但仍然出现相同的错误。这是错误

尝试设置 NODE_OPTIONS=--max_old_space_size=8172 增加内存，但错误依旧

【解决方案1】：

问题与 react-scripts 空间大小无关。

这是 EC2 实例大小问题，增加实例内存后它运行良好。

（注意：我试图在 EC2 免费层上运行它，它带有 8GB 的 SSD 和 0.8GB 的 RAM，在同一个实例上运行两个应用程序是不够的。但是在将实例更改为 2GB RAM 后，完全没有问题。）

【解决方案2】：

如果您使用的是 react-scripts 或 create-react-app，那么您可以尝试以下方法：

react-scripts --max_old_space_size=8172 开始
