aws-sdk（v 2.395.0）和react-native

Question

我正忙于升级已继承职责的React Native应用程序，并且在升级react native之后遇到一些构建问题。

我决定对旧项目进行核对（基于RN 0.53.3），并使用RN 0.58.2创建一个新项目。深入了解源代码之后，我在模拟器上的构建被捆绑在Metro捆绑器中的速度约为99％，该应用程序最终超时，告诉我它无法连接至开发服务器。

由于无法有效地调试问题，我一直在逐个文件，逐个代码地进行依赖以缩小问题的范围，导致这种挂起的第一个问题实际上是 aws-sdk npm模块。

仅添加了import AWS from 'aws-sdk/dist/aws-sdk-react-native'语句后，build就演示了概述的行为。

Failed to load bundle(http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false) with error:(Could not connect to development server.

Ensure the following:
- Node server is running and available on the same network - run 'npm start' from react-native root
- Node server URL is correctly set in AppDelegate
- WiFi is enabled and connected to the same network as the Node Server

URL: http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false The operation couldn’t be completed. (NSURLErrorDomain error -999.))
