Question

我正在与React Native和aws-sdk挣扎。我使用aws-sdk而不是aws-amplify的原因是：

aws-amplify does not support Using a pre-signed URL to upload a file

在aws-sdk安装npm并导入aws-sdk-react-native之前，我的项目运行良好（当aws-sdk版本为“ 2.369.0”时，此文件为4.3MB）

添加以下代码行之后：

const AWS = require("aws-sdk/dist/aws-sdk-react-native");

应用程序崩溃并显示错误消息：

我尝试了很多解决方案，例如：

increase-memory-limit

node --max-old-space-size=8192 index.js

如果您尝试了这些解决方案并且可以使用，请告诉我。也许我做错了事

如果您有任何建议，我总是愿意收到您的来信。

提前谢谢！

Answer 1

我可以将package.json更改为：

"scripts": {
    ...
  "start-max": "node --max-old-space-size=8192 node_modules/react-native/local-cli/cli.js start",
    ...
},

在终端运行中：“ npm run start-max”以8,192 MB启动节点服务器。然后正常运行您的项目：“ react-native run-android”。

Android版本：

在应用程序build.gradle文件中，添加以下行

project.ext.react = [
    entryFile: "index.js",
    nodeExecutableAndArgs: ["node", "--max-old-space-size=8192"]
]

享受！

Answer 2

通过 iOS 修复补充@LuongTruong 的回答。

iOS 版本：

转到（XCode 工作区 -> 项目 -> 构建阶段 -> 捆绑 React Native 代码和图像）

命令应该在顶部有这三行

export NODE_BINARY=node
export NODE_ARGS=--max-old-space-size=8192
export NODE_OPTIONS=--max-old-space-size=8192
