老師您好，我是新購課的學員，我是在Mac開發，ios環境是 xcode 9.4.1 android環境使用 android-studio3

依照課程所說 react-native init imoc_gp —version 0.40.0;

執行 react-native run-android沒有任何問題

但執行 react-native run-ios 卻沒辦法執行，出現以下文字

CompileC /Users/highlander/rn/imoc_gp/ios/build/Build/Intermediates.noindex/React.build/Debug-iphonesimulator/React.build/Objects-normal/x86_64/RCTJavaScriptLoader.o Base/RCTJavaScriptLoader.mm normal x86_64 objective-c++ com.apple.compilers.llvm.clang.1_0.compiler
