Summary

I encountered an issue while attempting to use my own npm package from a private GitHub repository in my project. To achieve this, I configured pre-install scripts to access the repository using an SSH key. The private key is encoded in Base64 and stored in the $DEPLOY_KEY variable.

./package.json

"scripts": {
  "start": "expo start --dev-client",
  "android": "expo run:android",
  "ios": "expo run:ios",
  "web": "expo start --web",
  "postinstall": "patch-package",
  "eas-build-pre-install": "./pre-install"
},

./pre-install

eval "$(ssh-agent -s)"
echo "$DEPLOY_KEY" | base64 -d > ~/.ssh/eas_id
chmod 0600 ~/.ssh/eas_id
ssh-add ~/.ssh/eas_id
touch ~/.ssh/config
echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config

However, this pre-install scripts result in this error at Install Independency phase.

npm ERR! code 128
npm ERR! An unknown git error occurred
npm ERR! command git --no-replace-objects ls-remote ssh://git@github.com/{organization-name}/{repository-name}.git
npm ERR! git@github.com: Permission denied (publickey).
npm ERR! fatal: Could not read from remote repository.
npm ERR! 
npm ERR! Please make sure you have the correct access rights
npm ERR! and the repository exists.

To solve this problem, I added npm ci at the last line of pre-install scripts. And this worked for me. But I wonder why I can't access to private repository at Install Independency phase. Does the configurations set at pre-install phase disappear at Install Independency phase?

Managed or bare?

✔ Check Expo config for common issues
✔ Check package.json for common issues
✔ Check dependencies for packages that should not be installed directly
✔ Check for issues with metro config
✔ Check for common project setup issues
✔ Check npm/ yarn versions
✔ Check Expo config (app.json/ app.config.js) schema
✖ Check that packages match versions required by installed Expo SDK
✔ Check for legacy global CLI installed locally
✔ Check that native modules do not use incompatible support packages
✔ Check that native modules use compatible support package versions for installed Expo SDK
✔ Check native tooling versions

I just need react-native-get-random-values@1.9.0 to use @aws-amplify/react-native, though expected version by Expo SDK is ~1.8.0.

Interesting, I've never encountered something like this before 🤔

We are not touching anything ssh related in our system between the PRE_INSTALL_HOOK and INSTALL_DEPENDENCIES phases 🤔
