Taro_React Native iOS 错误记录

cd到taro项目根目录，运行yarn install

npm run dev:rn

cd 到 rn_temp目录运行，生成jsbundle，需要在rn_temp目录下新建bundle文件夹

node ../node_modules/react-native/local-cli/cli.js bundle --entry-file ./rn_temp/index.js --bundle-output ./bundle/main.jsbundle --assets-dest ./bundle --dev false --platform ios

问题记录：

1.config.h' file not found

cd node_modules/react-native/third-party/glog-0.3.4

//  第一步。找到路径，进入glog-0.3.4文件里

../../scripts/ios-configure-glog.sh

//  第2步。

2.

报错为

Unknown argument type '__attribute__' in method -[RCTAppState getCurrentAppState:error:]. Extend RCTConvert to support this type.

这个BUG是Xcode.11引起的, 可以查看这个问题的提交记录，链接为：https://github.com/facebook/react-native/issues/25138

我们只需要找到RCTModuleMethod.mm这个文件,大约在93行左右

修改

static BOOL RCTParseUnused(const char **input)

{

  return RCTReadString(input, "__unused") ||

         RCTReadString(input, "__attribute__((__unused__))") ||

         RCTReadString(input, "__attribute__((unused))");

}

这个函数插入    RCTReadString(input, "__attribute__((__unused__))") ||  这行代码重新运行就行了。

3.项目运行无误，Archive出错

Cocoapods下的第三方库libReact.a多个路径

:-1: Multiple commands produce '/Users/***/Library/Developer/Xcode/DerivedData/sentryCpush-cvpqbragxhlzloeebvyoihyauasl/Build/Intermediates.noindex/ArchiveIntermediates/sentryCpush/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/libReact.a':

1) Target 'React' has a command with output '/Users/***/Library/Developer/Xcode/DerivedData/sentryCpush-cvpqbragxhlzloeebvyoihyauasl/Build/Intermediates.noindex/ArchiveIntermediates/sentryCpush/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/libReact.a'

2) Target 'React' has a command with output '/Users/***/Library/Developer/Xcode/DerivedData/sentryCpush-cvpqbragxhlzloeebvyoihyauasl/Build/Intermediates.noindex/ArchiveIntermediates/sentryCpush/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/libReact.a'

解决方法：

在Podfile中添加：

  post_installdo|installer|

    installer.pods_project.targets.eachdo|target|

      # The following is needed to ensure the "archive" step works in XCode.

      # It removes React & Yoga from the Pods project, as it is already included in the main project.

      # Without this, you'd see errors when you archive like:

      # "Multiple commands produce ... libReact.a"

      # "Multiple commands produce ... libyoga.a"

      targets_to_ignore = %w(React yoga)

      iftargets_to_ignore.include? target.name

        target.remove_from_project

      end

    end

  end

然后 pod install

4.react-native run-ios --simulator="iPhone 6"，运行时指定启动版本

5.'React/RCTBridgeModule.h' file not found

先clean，然后Scheme 选择React 先编译，编译成功后选择项目再次编译
