Podfile.lock missing when initial react-native run-ios

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-ios
error 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. Did you forget to run "pod install" ?
info Found Xcode project "emps_fe6.xcodeproj"

error Could not parse the simulator list output. Run CLI with --verbose flag for more details.

Here is the output of react native info:

    "socket.io-client": "2.1.1",
    "xcode": "^2.0.0"
  },

In the error message, there mentioned quite a few modules which are missing. 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:

error Cannot read property 'SPEC CHECKSUMS' of undefined. Run CLI with --verbose flag for more details.

For anybody with Mac M1 that nothing worked and still having the problem. They actually say at the docs you need to run those commands

sudo arch -x86_64 gem install ffi
arch -x86_64 pod install

when it ends will tell

[!] Please close any current Xcode sessions and use `MyApp.xcworkspace` for this project from now on.
Pod installation complete! There are 55 dependencies from the Podfile and 46 total pods installed.

if you go and now run pod install you will notice the deference

This solution would work when you are trying to START a project, I don't know if it would help while you are in one and come across this issue.

Here is what I did:

This worked for me.

I have tried many solutions. But finally tried something logical. I don't know why i didn't tried first :)

pod install doesn't work.It changes nothing. The problem is "Podfile" is there but not "Podfile.lock". Thats the problem. When we try install again, it is doing nothing because Podfile is there.

Solution is removing "Podfile" then pod install again. Then you will see both files "Podfile" and "Podfile.lock". After many hours of struggling, this was the solution for me and i have tried many thing :) Good luck to you all.

I had the same issue and I solve the problem using bellow approach.

Navigate to iOS folder and then run bellow command:

pod update

pod update command will update all dependency and generate a "Podfile.lock" file.

I had a similar issue and resolved it by jumping into the ios folder and running:

pod update

Doing this directly in the ios folder resulted in the generation of Podsfile.lock

Changing out of ios into the main directory I was able to then launch the app on an IOS simulator using:

npx react-native run-ios

Step 1:

sudo gem install cocoapods

Step 2:

cd ios && pod install && cd ../ && react-native run-ios

If you still get error while installing pods continue the below steps.

Step 3: Put this in console -> 

xcrun -k --sdk iphoneos --show-sdk-path

if the answer is

xcrun:_ error: SDK "iphoneos" cannot be located
xcrun: error: SDK "iphoneos" cannot be located
xcrun: error: unable to lookup item 'Path' in SDK 'iphoneos'

then put this: 

sudo xcode-select --switch /Applications/Xcode.app

Then install pod again

First install the cocoapods

sudo gem install cocoapods

Then run the below command on root folder

cd ios && pod install && cd ../ && react-native run-ios
