expo run:ios works fine but eas build --local fails

[thomasgrivet]

Hello!

I created a new managed project using expo init and then ran eas build:configure to create a eas.json file, in the development profile I added developmentClient: true and ran expo install expo-dev-client.
I created this project to be as clean as possible.

I also ran npm install -g eas-cli expo-cli to be up to date.

When I run expo run:ios, the ios folder gets created and the build is successful and open the app in my iOS simulator.
I would like to use eas build --profile development -p ios --local --clear-cache to create my artifact and not create any ios or android folder, however, when I run this command, I get the following output:

[RUN_FASTLANE] ▸ ** BUILD FAILED **
[RUN_FASTLANE] ▸ The following build commands failed:

Also, I tried running expo prebuild and building the project in Xcode and it works fine.

eas version’s output:

eas-cli/0.45.1 darwin-x64 node-v16.13.2

Did anyone get the same error? If so, did you manage to find a solution?

Thanks!

hi there! this is a react-native build issue. it can happen in certain conditions depending on how node is configured on your machine. these tips may be helpful reactjs - PhaseScriptExecution [CP-User] error in React Native - Stack Overflow. also see React Native's initial project doesn't run on IOS. · Issue #31249 · facebook/react-native · GitHub. if you are using nvm, i’d start with the suggestions oriented around that.

Thanks for the quick reply!
After some research, the problem did indeed come from my node setup and nvm.
For others having the same problem, I completely removed nvm, node and everything node-related from my system. I then re-installed nvm and ran a simple nvm install 16, this solved my build issue.
