That's just the error code, the actual error log is in the Issues section by clicking on the error.

If you're only having these issues when building via Xcode, and can successfully build from the example folder with `npm build:ios' from the terminal, the following may help, assuming it's the same problem I had where Xcode can't find npx:

1. In Xcode go to Product > Scheme > Edit Scheme
2. Select the “Build” tab on the left
3. In the “Pre-actions” and “Post-actions” sections, add the following line to set the correct path for npx:
   export PATH="$PATH:$(npm bin -g)"
4. Try to build again

Hello @mariojose96

I tried to run the build:ios in package.json but it runs like forever.

I follow your action but still receive the error

1. In Xcode go to Product > Scheme > Edit Scheme
2. Select the “Build” tab on the left
3. In the “Pre-actions” and “Post-actions” sections, add the following line to set the correct path for npx: export PATH="$PATH:$(npm bin -g)
4. Try to build again

Please take a look at the image for more information. I also select the error message, but there is no more information for me to investigate.

Hey @LuongTruong ,
I can reproduce the empty log as well in a new react-native module project using this command: npx create-react-native-library@latest react-native-awesome-module. But changing the build settings as suggested above solved it for me.

There's a good chance that it's just not grabbing the global npx path for you. I can see above that your path would resolve to "/usr/local/bin". Just export to that path directly with this command export PATH="$PATH:/usr/local/bin".

Your build settings Pre-actions should now look like this:

Add export PATH="$PATH:/usr/local/bin" to Post-Actions too, just to be sure.

Hey @mariojose96 , thanks for the comment. It helps me to build the app successfully.

I am closing the ticket since the issue is resolved.
