在ec2中为reactjs运行npm start时出错

Question

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上出错

也尝试过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以增加内存，但错误仍然相同

Answer 1

该问题与 react-scripts 空间大小无关。是EC2实例大小问题，增加实例内存后运行完美。（注意：我试图在带有 8GB SSD 和 0.8GB RAM 的 EC2 免费层上运行它，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，有完全没有问题。）

Answer 2

如果您使用的是 react-scripts 或 create-react-app，那么您可以尝试以下操作：反应脚本 --max_old_space_size=8172 开始
