npm install error when EAS build IOS

[naina-lele]

eas build --platform ios --profile prod keep throwing the error below. I spent quite some time re-searching but none of the answers i found helped.

Here are some of things I tried:

1. deleted node_module and package-lock.json, and npm install afterwards
2. npx clear-npx-cache
3. downgrading expo version to 46
   etc…

Hi @naina-lele

This seems to be a bug in npm related to peer dependencies.

See my comment on a related thread for a workaround:

eas build fail - showing "Cannot read properties of null (reading 'children')"

Are you using this? You don’t have react-dom or react-native-web, so maybe not unless maybe you’re bundling some stuff to load in a webview? If you’re not using it you might want to remove it. It should of course not be causing problems, but generally best to remove things you don’t need. Also, if you do need it it really belongs in devDependencies rather than dependencies. But that’s not the cause of the problem. If I try this with your deps it works for me. I was using yarn instead of npm, …

Thank you @wodin , not sure if it’s a smart work around but adding "eas-build-pre-install": "npm config set legacy-peer-deps true" to script fixed my issue. The issue was def with npm related to peer dependencies.
