环境

Npm：5.5.1
react-native-cli: 2.0.1
本机反应：0.45.1
React Native Navigation 版本：最新
平台（iOS、Android 或两者？）：(MacOS Sierra:10.12.6 (16G29,两者)
设备信息（Simulator/Device？OS版本？Debug/Release？）：版本10.0（SimulatorApp-829.6 CoreSimulator-494.22.3）/Debug

AppDelegate.m:

#import "AppDelegate.h"
#import <React/RCTBundleURLProvider.h>

// **********************************************

#import "RCCManager.h"

// IMPORTANT: if you're getting an Xcode error that RCCManager.h isn't found, you've probably ran "npm install"
// with npm ver 2. You'll need to "npm install" with npm 3 (see https://github.com/wix/react-native-navigation/issues/1)

#import <React/RCTRootView.h>

Answer 1

正常情况下，错误提示 React Native 开发者服务器未运行ning。默认情况下，它应该打开另一个带有开发人员服务器的终端以进行本机反应。有时它会挂在那里，你可以在另一个终端中重新运行 react-native 运行-ios ，而你已经打开了，如果那不尝试 rm -rf ~ /.rcache 并删除 ios build

Answer 2

第一步

酿造更新
brew 安装守望者

如果第一步失败尝试第二步

brew 安装节点
brew 安装守望者
brew link automake pcre
npm install -g react-native-cli
出口ANDROID_HOME=~/Library/Android/sdk
导出路径=${路径}:${ANDROID_HOME}
react-native 运行-android
