【问题描述】：

当我初始化一个项目然后运行时，我是 react-native 的新手

react-native run-ios

我收到此错误

** BUILD FAILED **

Installing build/Build/Products/Debug-iphonesimulator/AwesomeProject.app
An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2):
Failed to install the requested application
An application bundle was not found at the provided path.

节点-v 6.5.0

react-native-cli: 1.0.0

反应原生：0.32.1

xcode 8 测试版 5

【参考方案1】：

也许您的版本太新或不是最新的？

我的 run-ios 工作

节点-v v6.0.0

反应原生 -v react-native-cli: 0.2.0

您是否尝试过直接在 xcode 中运行您的项目？可能会给你更多线索。

【讨论】：

当我尝试使用 xcode 构建它时，我在 RCTWebSocket hello/node_modules/react-native/Libraries/WebSocket/RCTSRWebSocket.m:494:3: Ignoring return value of function declaration with warn_unused_result 中遇到两个错误属性/hello/node_modules/react-native/Libraries/WebSocket/RCTSRWebSocket.m:1334:5：忽略使用warn_unused_result属性声明的函数的返回值

你能解决它吗@MuhammadMohsinTariq 即使我有同样的问题，我也不知道如何解决它
