在 Ubuntu 20 ec2 实例中设置 Ionic 环境时出错

Question

我正在尝试在 ubuntu 服务器上生成 Android 和 IOS 平台文件夹，以便我可以将它们传输到能够构建 . apk 和 .ipa 相同。我使用 Ionic CLI 6.18.1、@ionic/agular 5.9.3、cordova CLI: 10.0.0 和节点 14.18.1 成功地做到了这一点，但有很多使用 Ionic CLI 6.18.1、@ionic/agular 6.0.8、cordova CLI：11.0.0 和节点 16.14.0 升级 项目时出现问题。

我想详细了解为什么会发生这种情况，以及一些 document/video 我可以参考以解决同样的问题。

I have added the detailed error at the bottom

我经常遇到的错误，仅在 ec2 实例中是：

致命错误：达到堆限制分配失败 - JavaScript 堆内存不足 [e1]
新的 SubprocessError [e2] 处出错

我尝试过的解决方案：

解决致命错误：达到堆限制分配失败 - JavaScript 堆内存不足

设置NODE_OPTIONS=--max_old_space_size=8192
已更改 package.json

“脚本”：{ "ng-high-memory": "node --max_old_space_size=8000 ./node_modules/@angular/cli/bin/ng build --configuration=prod", }

npm 运行 ng-高内存

详细错误：

[e1] 致命错误：达到堆限制分配失败 - JavaScript 堆内存不足

Answer 1

我通过将 RAM 从 1 GB 升级到 2 GB (t2.micro - t2.small) 解决了这个问题。

我们通过复制相同环境在 VM（虚拟机）中进行运行系列测试得出了这个结论。

谢谢。
