最近在学习React Native 参考官网教程 使用最新版本(0.61) 基本没遇到什么问题
尝试使用老版本 0.58 在构建一遍 踩到了许多坑 在此记录一下

1. react-native run-ios 无法启动模拟器

// 遇到问题
Could not find iPhone X simulator

Error: Could not find iPhone X simulator
    at Promise.then.udid.udid (/Users/sobot/Documents/react-native-app/rn_0_58_4/node_modules/react-native/local-cli/runIOS/runIOS.js:149:13)

    at /Users/sobot/Documents/react-native-app/rn_0_58_4/node_modules/react-native/local-cli/cliEntry.js:117:22

// 解决方案
// 找到 node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js 注释掉以下代码
if (
  simulator.availability !== '(available)' &&
  simulator.isAvailable !== 'YES'
) {
  continue;
}

// 重新 react-native run-ios 解决

2. ios/build/ModuleCache.noindex/GDNYEK3GNWBZ/WebKit-3M3AFHBPPA3AE-1a58cd7a.pcm.tmp' 解决完上一个模拟器问题之后 继续执行 出现这个报错看问题描述貌似是备份之类的出错 取消再次执行就不报错了

// 解决完上一个模拟器问题之后 继续执行 出现这个报错

3. 模拟器红屏 Unknown argument type 'attribute' in method -[RCTAppState getCurrentAppState:error:]. Extend RCTConvert to support this type.

         RCTReadString(input, "__attribute__((__unused__))") || // 增加这行解决
         RCTReadString(input, "__attribute__((unused))");
}

4. 安装react-native-video 报错 TypeError: undefined is not an object (evaluating 'RCTVideoInstance.Constants')

解决方案

1. cd ios // 进入ios目录
2. pod init ./rn_0_58_4.xcodeproj/ // 初始化cocospods 后面的xcodeproj是当前路径下的
3. 编辑Podfile

// 使用以下内容覆盖Podfile

project './rn_0_58_4.xcodeproj/'

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'

target 'rn_0_58_4' do
  # Comment the next line if you don't want to use dynamic frameworks
  # use_frameworks!
  pod 'React', :path => '../node_modules/react-native/'
  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
  pod 'react-native-video', :path => '../node_modules/react-native-video/react-native-video.podspec'

  # Pods for rn_0_58_4
end

4. cd .. // 回到项目根目录
5. react-native link react-native-video // 链接到native
6. cd ios //
7. pod install --verbose // 安装原生依赖 
8. react-native run-ios // 运行成功

5. run-ios 时候一直下载内容 是因为 /User/username/.rncache/ 缺少版本需要的依赖

// 这块改路径版本
