I am setting up IOS dev for React Native (0.61) app which has the working android version. What I did was to copy src of components and package.json file after react native environment is setup by following online post (installed xcode command line tool 10.2). But launching run-ios failed:
$ react-native run-ioserror Could not find "Podfile.lock" at /Users/mine/Documents/code/js/emps_fe6/ios/Podfile.lock. Did you run "pod install" in iOS directory?error Could not find the following native modules: RNCAsyncStorage, RNDeviceInfo, RNGestureHandler, RNKeychain, BVLinearGradient, RNLocalize, RNReanimated, RNVectorIcons, react-native-video.

But those modules have been installed as it shows in the package.json. I am not sure about what the error message means. Also I installed the simctl but scrum simctl still can not find it. I am using VS Code as IDE.
UPDATE:
created an empty Podfile.lock under /ios, the error becomes when run-ios:
