EAS Build Permission Denied Error When Running eas-build-pre-install Script on

Question

I'm encountering a "Permission denied" error when EAS Build tries to run my eas-build-pre-install script during the build process. I have a script set up to install pnpm specifically for Android builds. The script content in scripts/eas-pre-install is:

#!/bin/bash

if [[ "$EAS_BUILD_PLATFORM" == "android" ]]; then
  npm install -g [email protected]
  pnpm --version
fi

In my package.json, I have defined the eas-build-pre-install script as follows:

"scripts": {
  "eas-build-pre-install": "./scripts/eas-pre-install"
}

#!/bin/bash

if [[ "$EAS_BUILD_PLATFORM" == "android" ]]; then
  npm install -g [email protected]
  pnpm --version
fi

Script 'eas-build-pre-install' is present in package.json, running it...

> [email protected] eas-build-pre-install /home/expo/workingdir/build

> ./scripts/eas-pre-install

sh: 1: ./scripts/eas-pre-install: Permission denied

ELIFECYCLE  Command failed with exit code 126.

WARN   Local package.json exists, but node_modules missing, did you mean to install?

pnpm run eas-build-pre-install exited with non-zero code: 1

Answer 1

Ensure that the script pre-install has the execute permission. You can use the following command to grant execute permission:

chmod +x pre-install

After running this command, try executing your script again.
