aws-sdk（v 2.395.0）和react-native [英] aws-sdk (v 2.395.0) and react-native

问题描述

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。

决定核销旧项目（基于RN 0.53.3），并使用RN 0.58.2创建新项目。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。

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，而第一个导致此问题挂起的问题实际上是 aws-sdk npm模块。

简单地从'aws-sdk / dist添加 import AWS / aws-sdk-react-native'语句，该示例演示了概述的行为。

 无法加载捆绑包（http：// localhost：8081 / index.bundle？platform = ios& dev = true& minify = false），错误：（无法连接到开发服务器。
 
确保以下各项：
-节点服务器正在运行并且在同一网络上可用-从react-运行'npm start'-本机根
-在AppDelegate中正确设置了节点服务器URL 
-启用了WiFi，并将其与节点服务器
 
连接到同一网络URL：http：// localhost：8081 /index.bundle?platform=ios&dev=true&minify=false无法完成操作。（NSURLErrorDomain错误-999。））

Am in the throes of upgrading a react native application that I've inherited responsibilities for, and am coming across some build issues after upgrading react native.

I have decided to nuke the old project (based on RN 0.53.3) and created a new project with RN 0.58.2. After shoe horning the source in, my builds to simulator were getting hung up in the metro bundler at ~99%, with the application eventually timing out telling me that it Could not connect to development server. 

Unable to effectively debug the issue, I have been going file by file, code dependency by dependency to narrow down the issue, and the first issue that is causing this hang up is actually the aws-sdk npm module.

After simply adding the import AWS from 'aws-sdk/dist/aws-sdk-react-native' statement, build demonstrates the outlined behavior. 
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.))
